However in a match against Hearts in the opening game of the season, he conceded two goals despite producing saves throughout the game, as Rangers lost 2–1. Niemi appeared in the first leg of the second qualifying round of the UEFA Cup against PAOK and kept a clean sheet clean to help the club win 2–0. Following this, he was dropped from the squad for the next three months.

Following this, he became the club's first choice goalkeeper for the rest of the year. On 21 November 1998, Niemi was in goal against Celtic when he conceded five goals and lost as a result, which Helsingin Sanomat described Rangers’ performance as “the most humiliating defeats in the Scottish Premier League history”. A week later, Niemi started the Scottish League Cup final and was able to make up his amends when he helped the club beat St Johnstone 2–1 to win the tournament. However, Stefan Klos was signed in December 1998 and immediately became Rangers’ first choice, demoting Niemi to the bench. Rangers won the Scottish Premier League in the 1998–99 season, but he only contributed seven league appearances.
Niemi's demotion to the substitute bench and eventual third choice status led to his contemplate his future at the club.

Niemi also had a brief loan spell at Charlton Athletic late in 1999.

### Hearts

The start of the 2000–01 season saw Niemi make a good start for Hearts by keeping three clean sheets against rivals, Hibernian and both legs in the UEFA Cup qualification against ÍBV Vestmannaeyjar. During the match against Hibernian, he was hit in a head with a plastic cup by a Hibernian supporter. Niemi played in European competition for the club against opponents such as Stuttgart, as Hearts would be eliminated by away goal following a 3–3 draw on aggregate. Despite losing 1–0 against his former club, Rangers on 17 September 2000, newspaper The Herald said about his performance: "he found himself playing spectator for much of the 90 minutes as the opposition sat back, not through choice, but because they had no alternative amid an incessant attack ". By mid–November, Niemi conceded fourteen goals in the last three matches, including one in a 5–2 loss against Celtic in the quarter-finals of the Scottish League Cup, but he remained the club's first choice goalkeeper. Niemi's performance throughout the 2000–01 season was praised by his former teammate, Goram, and manager Craig Levein. In a match against Kilmarnock on 9 December 2000, he set up a goal for Andy Kirk, who scored twice, in a 3–0 win. Having conceded a total of seven goals against Henrik Larsson in the 2000–01 season, Niemi described him as "...among the best he has ever played against". Niemi then kept three consecutive clean sheets between 14 March 2001 and 31 March 2001. For his performance, he was named April's Player of the month.

Niemi continued to maintain his good form throughout the season. The Herald Scotland commented on his performance, saying: "Selling prized assets has become a ritual, one that is almost certain to continue with Antti Niemi. Had it not been for the Finnish goalkeeper in the last two weeks, Hearts could easily have conceded around." However, he suffered a finger injury that saw him out for four weeks. On 23 January 2002, Niemi made his return from injury, in a 2–0 loss against Celtic. Following his return, he resumed his role as the club's first choice goalkeeper role for the rest of the season.

Niemi put in some fantastic performances which helped prevent Hearts from even worse Derby thrashings than the 0-3 and 6-2 hammerings, whom he was on the end of. Niemi also became famous in Scotland for his ability to save penalties, demonstrating this skill when saving from Dundee United's Charlie Miller and Dunfermline Athletic's Scott Thomson. In a more light-hearted incident, Niemi was also famously during his time at Hearts the subject of a call during a phone-in on radio channel talkSPORT, in which a Scottish fan queried why Niemi had not been called up to the Scotland national team. When presenter Arthur Albiston told the caller that Niemi was in fact Finnish, the caller replied "He's no' finish', he's only 28!" Upon his retirement from professional football, he recalled his time at Hearts, quoting: "it was all good. Looking back, everything went so well – it was a lovely club, the team was doing well, I was playing well and we had a good manager in Jim Jefferies".

### Southampton

After three seasons in Edinburgh, Niemi agreed a move to Premiership side Southampton on 22 August 2002 for a fee of £2 million. The move was officially announced five days later. Upon joining the club, he was linked up with manager Gordon Strachan, who tried to sign him in 1997 whilst as a manager of Coventry City. However, the move angered Hearts supporters, prompting the club's chief executive Chris Robinson to defend the sale. But the signings of Niemi and Michael Svensson caused the Saints to lose £3.5 million for the first half of the financial year.
Niemi made his debut for Southampton against his former club, Charlton Athletic on 21 September 2002 and kept a clean sheet, including saving a 30-yard free-kick from Claus Jensen and a 25-yard shot from Chris Bart-Williams, in a 0–0 draw. Since joining the club, Niemi immediately dispatched the first choice goalkeeper role from Paul Jones. He also produced his good form at Southampton, including against Aston Villa, Arsenal and West Ham United. However, Niemi suffered a knee injury that saw him out for two matches. But on 21 December 2002, he made his return from injury, in a 1–1 against Leeds United. Following his return from injury, Niemi regained his first choice goalkeeper role for the club. He said the Southampton's aim was to qualify for Europe, due to the inspiration from manager Strachan. By the end of February, Niemi conceded twenty–six goals in all competitions for Southampton. He contributed to the club's FA Cup runs to the quarter-finals, playing five times. In a game against Fulham in the 2002–03 season, Niemi came up for a corner in injury time with Southampton trailing 2–1. The ball fell at his feet and he crashed a shot against the crossbar, and Michael Svensson was able to turn in the rebound, salvaging a draw. However, Niemi suffered a knee injury that saw him out for three matches. On 3 May 2003, he returned from injury to be included to the starting line–up and kept a clean sheet, in a 0–0 draw against Bolton Wanderers. After missing the remaining two matches due "to precaution with a recurring knee problem", Niemi played for Southampton in the 2003 FA Cup final against Arsenal, which the Saints lost 1–0; Niemi became the first goalkeeper to be substituted in an FA Cup Final when he was replaced by Paul Jones during the game due to a calf injury. In his first season at the club, Niemi made thirty–three appearances in all competitions.
Ahead of the 2003–04 season, Niemi was linked with a move to Premiership's champions, Manchester United, but he ended up staying at Southampton, due to his calf injury. Niemi spent first month to the season, recovering from his injury. By late–August, Niemi returned to training and spent the following month on the substitute bench. On 4 October 2003, he made his first appearance of the season against Newcastle United and was faultless from conceding a 43rd-minute goal from Alan Shearer, as the club lost 1–0. His second appearance of the season came in the second leg of the UEFA Cup first round against FC Steaua București and conceded an 83rd-minute goal from Claudiu Răducanu, as Southampton lost 1–0 and was eliminated from the tournament. Niemi then kept clean consecutive clean sheets between 19 October 2003 and 28 October 2003. However during a 3–0 win against Bristol City in the third round of the League Cup, he suffered a groin injury and was substituted at half-time. Niemi made his return from injury against Bolton Wanderers on 8 November 2003 and kept a clean sheet, as Southampton drew 0–0. After the match, local newspaper Southern Daily Echo praised his performance, calling him "the club's best player in the 2003–04 season" so far. Since returning from injury, he, once again, dispatched the first choice goalkeeper role from Paul Jones. During a 2–0 loss against Arsenal on 10 February 2004, he was booked in the last minute of the match "for dissent towards the linesman". After the match, Niemi said he was wrong to receive a booking and that "it was out of character for him to lose his cool". Following Strachan's departure from the club, Niemi said Southampton need to adjust without him and was replaced by Paul Sturrock. In a match against Blackburn Rovers on 28 February 2004, he produced good performances and "thwarted striker Andy Cole on a number of occasions and his array of saves" before conceding a goal from him, as the club drew 1–1. In a follow–up match against Liverpool, Niemi saved a Michael Owen's penalty to help his team to a 2–0 win. After the match, he was named man of the match. However, Niemi missed the last two matches of the season, due to a virus. At the end of the 2003–004 season, he went on to make thirty–three appearances in all competitions. Local newspaper, Southern Daily Echo, praised Niemi's performance, saying: "It's a difficult quality to explain or quantify, but like many great players, the Finn has a real presence. He has it both on and off the field. But, for all his serenity, it is the agility, positioning and breathtaking shot-stopping ability that makes Niemi such a good goalkeeper. Even when he makes an amazing save, not a blade of hair ever seems to move out of place! And anyone who seriously thinks there has been a better keeper in the league this season has simply not seen enough of Southampton in 2003–04 season. The stats which place him as the best shot-stopper in the top-flight back this up and it is certainly no exaggeration to suggest a relegation battle could have threatened without him." Niemi was also awarded the club's Player of the Season.
Ahead of the 2004–05 season, there was much speculation regarding Niemi's future at Southampton with a host of leading Premier League clubs rumoured to be interested in his services, such as Manchester United and Arsenal. This led the club to open talks with him over a new contract. He, himself, wanted to stay at Southampton. In the first month to the season, he signed a contract extension with Southampton, keeping him until 2008. After losing 2–0 against Aston Villa in the opening game of the season, he was involved in an altercation with David Prutton halfway through the second half. In a post-match interview, Prutton played down suggestions of dressing room tension, stating that he and Niemi made up after the game. Niemi was blameless for the club's poor start to the 2004–05 season, conceding ten goals in the first ten league matches and picking up six points. However, he suffered a knee injury that kept him out for a month. Upon returning from injury, Niemi reflected on his performance in the 2004–05 season so far, saying: "We have to pick up points sooner rather than later. The season has been okay personally, but right now, no one can really say 'I've done well'." He made his return from injury against Middlesbrough on 11 December 2004 and conceded two late goals, as Southampton went on to draw 2–2. After the match, manager Harry Redknapp praised Niemi's performance, saying: "Antti Niemi made a terrific save. He's a top class keeper and he's important for us." However in a follow–up match against Tottenham Hotspur, Niemi conceded five goals, and was blameless for his performance, as the club lost 5–1. With Premier League clubs continuously remain interested in signing him in the January transfer window, he ruled out leaving Southampton. During a 2–1 loss against Newcastle United on 15 January 2005, Niemi suffered a knee injury and was substituted in the 6th minute. But it turns out the knee injury was a bruising and returned to the starting line–up against Liverpool on 22 January 2005 and kept a clean sheet, in a 2–0 win. However, he suffered a knee injury once again that saw him out for a month. It wasn't until on 18 March 2005 when Niemi made his return from injury and started the whole game, in a 3–1 win against Middlesbrough. After missing one match due to a hip injury, he spoke out about the determination of the club's survival to retain their Premiership status. In the last game of the season, Niemi was unable to help Southampton avoid relegation despite his best effort after losing 2–1 against Manchester United. At the end of the 2004–05 season, he went on to make thirty–two appearances in all competitions. Reflecting on the season, Niemi described the club's relegation as his "first bad experience in British football" and "average at best".
Ahead of the 2005–06 season, Niemi's future at Southampton was uncertain following their relegation to the Championship. He was linked to a move to Celtic, with a chance of reuniting with manager Gordon Strachan, but they opted to sign Artur Boruc instead. In the end, Niemi stayed at the Saints. He started the season by keeping four clean sheets in the first month to the season, including three consecutive clean sheets. Niemi, once again, kept another three consecutive clean sheets between 22 October 2005 and 5 November 2005. Despite the club was unable to establish consistency needed to make the club's promotion contenders, manager Redknapp praised his performance, saying: "He's one of the best goalkeepers playing in this country, let alone this league. Niemi enjoyed it here and, though there was talk of Celtic wanting him in the summer, they got a good keeper, and it was good for us. He's not had a lot to do this season. We've never been under much pressure." However, Niemi suffered an illness that saw him out for two matches at the end of the year. It wasn't until on 31 December 2005 when he returned from injury against Cardiff City and captained Southampton, as the club lost 2–1. By the time Niemi left Southampton, the club was in the mid-table, just outside of challenging for promotion, and made twenty–five appearances in all competitions.

In the 2006–07 season, Niemi fully established himself as Fulham's first choice goalkeeper. During a 1–1 draw against Portsmouth on 11 November 2006, he produced a number of saves before conceding a goal from Andy Cole. After the match, manager Chris Coleman praised Niemi's performance. However, he suffered a knee injury that saw him out for two matches. It wasn't until on 18 December 2006 when Niemi made his return from injury against Middlesbrough and helped the club win 2–1. However, Niemi was badly hurt in a freak accident during a match against Watford on 1 January 2007 when rushing out to head the ball; he toppled over his own defender, Carlos Bocanegra, and landed on his head. He was taken from the field of play on a stretcher after ten minutes of treatment but was later cleared of any spinal injury. He was released from hospital later that night with only ligament and muscle damage to the neck. However, Niemi's return was short–lived when he injured himself in the warm-up prior to the match against Newcastle United on 3 February 2007, which Fulham won 2–1. On 3 March 2007, Niemi made his return from injury, in a 1–1 draw against Aston Villa. He regained his first choice goalkeeper role for the club for the rest of the 2006–07 season.

The club secured the Cottagers' survival, which was confirmed on the final day of the season with a 1–0 win over Portsmouth. At the end of the 2007–08 season, he went on to make twenty–three appearances in all competitions.

Two days later on 17 October 2007, Niemi started the match and kept a clean sheet throughout the match, in a 0–0 draw, which was capped 67 times by his country before this.

## Coaching career

On 2 March 2010, Niemi joined Finland's national team as a goalkeeping coach to start his coaching career. While working on the role, he mentored Jesse Joronen and Lukas Hradecky.
On 3 January 2013, his first club and reigning Veikkausliiga champions HJK announced that they had appointed Niemi as the club's goalkeeping coach and that he would continue his duties with the national team. Having spend a year, he had a brief stint in FC Honka coaching staff. On 27 June 2014, Niemi was appointed goalkeeper coach at Championship side Brighton & Hove Albion by former Finland teammate Sami Hyypiä. He remained at the club, even after the sacking of Hyypiä in December 2014. At the end of the 2014–15 season, Niemi left Brighton & Hove Albion, citing personal reasons and returned to Finland.
On 26 January 2021, Niemi was appointed in the coaching staff of HIFK, after a request of then head coach Joaquín Gómez. At the end of the 2021 season, he left the club. On 21 June 2024, Niemi joined Greek side Volos, where he was reunited with Joaquín Gómez.

## Personal life

Having played in England for the rest of his football career, Niemi is fluent in English. He is married and is a father of two children. Following his end of his professional football career, Niemi returned to Finland to focus on his family while balancing his role as a goalkeeper coach.
In his spare time, Niemi plays the bass and even said that since as a teenager, he wanted to play in a band. It was announced on 25 January 2011 that MTV3 would release a DVD featuring highlights of Niemi's professional football career.
