**Franciscus "Frank" de Boer** (Dutch pronunciation: [ˈfrɑŋg də ˈbuːr];[2] born 15 May 1970) is a Dutch football manager who is currently the head coach of Atlanta United. A former defender, De Boer spent most of his professional playing career with Ajax, winning five Eredivisie titles, two KNVB Cups, three Super Cups, one UEFA Cup, one UEFA Champions League and one Intercontinental Cup. He later spent five years at Barcelona, where he won the 1998–99 La Liga title, before retiring after short spells at Galatasaray, Rangers, Al-Rayyan and Al-Shamal.

De Boer is the second most capped outfield player in the history of the Netherlands national team, with 112 caps.[3] He captained the *Oranje* to the semi-finals of both the 1998 FIFA World Cup and UEFA Euro 2000. He is the twin brother of Ronald de Boer, with whom he was a teammate at Ajax, Barcelona, Rangers, Al-Rayyan, Al-Shamal and the Netherlands national team.

After retiring from playing, De Boer went into management with the Ajax youth team and as assistant to Bert van Marwijk with the Netherlands national team. In December 2010, he took over as manager of Ajax and went on to win the Eredivisie title in his first season. In 2013, he received the Rinus Michels Award for manager of the year in the Netherlands after leading Ajax to their third successive Eredivisie title.[4] The following year, he became the first manager to win four consecutive Eredivisie titles.[3] He then had brief spells managing in Serie A with Internazionale in 2016 and Crystal Palace in the Premier League in 2017.

## Club career

### Ajax

De Boer was a pallbearer for his Ajax teammate Lloyd Doesburg, who died in Surinam Airways Flight 764.

De Boer began his career as a left back at Ajax before switching to centre-back, a position he made his own for many years in the national team. He won both the 1991–92 UEFA Cup and 1994–95 UEFA Champions League while at Ajax, in addition to five Eredivisie titles and two KNVB Cups. However, after signing a six-year contract extension with Ajax for the 1998–99 season, he and his twin brother Ronald
 took successful legal action to have it voided. Ajax had a verbal
agreement that if a lucrative offer for one brother came by, he would be
 released provided the other stayed. Ajax, however, apparently backed
down on that agreement after floating the club on the stock market and
pledging to shareholders that it would hold both of the De Boers and
build around them a team to recapture the Champions League.[5]

### Barcelona

In January 1999, Frank and Ronald de Boer signed for Spanish La Liga club Barcelona for £22 million, joining their former Ajax manager Louis van Gaal at the Camp Nou.[6] After winning the 1998–99 La Liga title,
 they were unable to repeat their earlier triumphs. In 2000, Van Gaal
was sacked by Barcelona and Frank suffered the ignominy of testing
positive for the banned substance nandrolone a year later. He was suspended but he was reinstated after a successful appeal.[7]

### Later career

De Boer briefly moved to Galatasaray in the summer of 2003 before joining his brother at Rangers in January 2004. He made a total of 17 appearances for Rangers, scoring two goals. The De Boer brothers left Rangers after UEFA Euro 2004 to play the rest of their football careers in Qatar with Al-Rayyan. De Boer announced his retirement from football in April 2006.

## International career

Having represented his national team 112 times,[8] he was the most capped player in the history of the Netherlands national team, until Edwin van der Sar surpassed him. De Boer made his debut for the Netherlands in September 1990 against Italy.

De Boer also played for the Netherlands in the 1994 and 1998 FIFA World Cups, and the 1992, 2000 and 2004 UEFA European Championships. He is well-remembered for the arching 60-yard pass which allowed Dennis Bergkamp to score the last-minute goal that eliminated Argentina in the quarter-finals of the 1998 World Cup.[9][10][11]
 During Euro 2000, hosted in his home country and Belgium, De Boer
reached another semi-final with the Dutch team. De Boer missed an
important penalty kick in the first half of the semi-finals against
10-man Italy and another in the penalty shootout, which led to the
Netherlands' elimination from the tournament.[12]

On 29 March 2003, in a home match against Czech Republic, De Boer became the first Dutch male footballer to gain 100 caps.[13] He ended his international career after an injury forced him to be replaced in a quarter-final match with Sweden at Euro 2004.[14] The injury ruled him out from the semi-final match against Portugal, which the Netherlands lost 2–1.[15][16]

## Style of play

A
 talented and well-rounded world-class defender, in addition to his
defensive skills, De Boer was also known for his pace, technical
ability, accurate passing, and leadership, which enabled him to carry
the ball out of defence, play it out from the back, or contribute to his
 team's offensive plays by initiating attacks and creating chances for
strikers with long balls. A versatile, intelligent, and elegant
left-footed defender, with an ability to read the game and intercept
loose balls, he was capable of playing both on the left and in the centre, and was even deployed as a sweeper. He was also a dangerous set-piece taker, renowned for his accurate bending free kicks from anywhere around the penalty area.[17][18][19][20][21][22][23]

## Managerial career

### Entering management

In 2007, De Boer took up a coaching role at his former club Ajax where he was in charge of the club's youth sector. During the 2010 World Cup, he was the assistant of the Netherlands national football team to manager Bert van Marwijk, together with retired player Phillip Cocu.[24] The Dutch team reached the final of the tournament, losing to Spain.

### Ajax

De Boer with Ajax in 2011.

On 6 December 2010, after the resignation of Martin Jol, De Boer was appointed caretaker manager of Ajax until the winter break. His first game in charge was a Champions League match against Milan at the San Siro, a match Ajax won 2–0 through goals from Demy de Zeeuw and Toby Alderweireld.[25] De Boer then went on to help Ajax become champions of the Eredivisie for the 2010–11 season in a 3–1 home victory over Twente, the champions of the previous year,
 on the final matchday, making the first year of his professional
coaching career a golden one. "I couldn't have wished for a more
beautiful birthday present", said De Boer, as the club's 30th
championship was won on his 41st birthday.[26]

In two-and-a-half years at the helm of Ajax, De Boer won three
championships, making eight in total (when including the five that he
won as a player). According to reports, De Boer was offered the chance
to interview for the Liverpool
 job but turned it down to remain with Ajax. "I am honoured by the
request [from Liverpool] but I have only just started with Ajax", he
said.[27] In 2013, De Boer received the Rinus Michels Award for manager of the year in the Netherlands after leading Ajax to their third successive Eredivisie title.[4]

On 27 April 2014, De Boer won his fourth successive Eredivisie
title with Ajax, the first manager ever to achieve this in the Dutch
league. Moreover, it marked the first time Ajax has ever won four
successive Eredivisie titles. De Boer has now won a total of nine
Eredivisie championships with Ajax as a player and manager, another
record; Johan Cruyff, Sjaak Swart and Jack Reynolds all won eight Eredivisie championships with Ajax. Ajax finished the 2014–15 Eredivisie in second position, a massive 17 points behind champions PSV.

On 11 May 2016, De Boer announced his resignation as manager of
Ajax following a disappointing season when Ajax again lost out on the Eredivisie title to PSV on the final matchday of the season.[28]

### Internazionale

On 9 August 2016, after the departure of Roberto Mancini, De Boer signed a three-year contract with Internazionale for the start of the 2016–17 season.[29] De Boer's first match in charge was Inter's final pre-season friendly, a 2–0 win against Celtic on 13 August, played on neutral ground at Thomond Park, Republic of Ireland.[30]

The club management board also approved expensive signings João Mário and Gabriel Barbosa for the team and De Boer (they were in fact linked to Mancini and Inter in July),[31] and the return to Turkey of recent acquisition Caner Erkin in the last days of transfer window. Gabriel, however, was rarely used in Serie A matches and could not be registered in European competitions due to a penalty imposed on Inter for breaching UEFA Financial Fair Play Regulations in previous seasons.

De Boer's first competitive match was a 2–0 away loss to Chievo on 21 August.[32] After the match, De Boer was criticized for using a three-man defence, a style that he had never used while at Ajax.[32] Milan-based newspaper *Corriere della Sera* went as far as calling Inter's performance a "disaster".[33] Fortunes soon turned, however, as Inter drew 1–1 against Palermo on 28 August, before winning three games in a row, against Pescara, title-holders Juventus and Empoli.[34] The win against Juventus was highly praised, with De Boer being lauded for substituting Éder for Ivan Perišić, who provided the winning goal.[35] Inter's form would not last long, as the club would go on to lose against Roma, Cagliari and Atalanta.

Inter also struggled in the UEFA Europa League under De Boer, as they lost the opening match 0–2 at home against Israeli team Hapoel Be'er Sheva on 15 September,[36] and 3–1 against Sparta Prague on 29 September.[37]
 Inter would then go on to finish last in their group with a total of
six points, with three points under De Boer and another three under his
successor.

Following a run of four defeats in the last five Serie A matches,
 which left Inter in 12th place in Serie A, De Boer was sacked on 1
November, having been in charge for only 85 days.[38] His last match was a 1–0 loss to Sampdoria on 30 October.[39]
 Ironically, during a press interview in the annual general meeting of
the shareholders of Internazionale on 28 October, CEO Michael
Bolingbroke had confirmed that the club was 100% backing De Boer.[40] (Bolingbroke himself resigned a few days later. Liu Jun, vice-president of sister company Suning Sports, replaced Bolingbroke.)

 ***Inter sacks de Boer in 85 days***

De Boer argued that he "needed more time" in order to make a mark as manager at Inter, and thanked his fans on his Twitter profile for the support.[41][42] He was replaced by former Lazio manager Stefano Pioli on 8 November, the ninth manager Inter have appointed since winning the Treble in 2010 under José Mourinho.
 Following Pioli's initial struggles at Inter, De Boer has hit back at
the lack of leadership following Suning's takeover of Inter, which he
credits for the lack of trust he was given while there.[43]

### Crystal Palace

On 26 June 2017, De Boer was announced as the new manager of Premier League side Crystal Palace, replacing the recently resigned Sam Allardyce. He signed a three-year deal with the South London club,[44][45]
 but was sacked 10 weeks later when Palace lost their first four league
matches of the season without scoring a single goal – the first team in
93 years to have begun a top-flight season in such a fashion.[46] He left having managed the team for only 450 minutes of game time of a Premier League team, making it the shortest reign of the Premier League era (in terms of number of matches, rather than number of days).[47] De Boer's only win came in an EFL Cup second-round game, in which Crystal Palace won 2–1 against Ipswich Town.[46][48] He was replaced by Roy Hodgson.[49]

Whilst at the club, De Boer attempted to implement a
possession-based style of play; after his sacking, he criticised the
club's players for their resistance to his approach, arguing that the
club had signed only two players to fit his philosophy.[50] Palace winger Wilfried Zaha
 commented on De Boer's brief time at the club, stating "There wasn't
really the right mixture [of players] for the way we wanted to play."[51]
