Question: What former Northern Ireland international footballer did Freddie Steele bring in to play for Port Vale?

Context paragraphs:
1963–64 Port Vale F.C. season: The 1963–64 season was Port Vale's 52nd season of football in the Football League, and their fifth season in the Third Division.  Freddie Steele spent big on transfers, bringing in players such as Billy Bingham, Albert Cheesebrough, and Jackie Mudie.  However it was a disappointing season in the league and a disaster financially.  The highlights of the season came in the FA Cup, where Vale beat top-flight Birmingham City at St Andrew's, and drew 0–0 with Liverpool at Anfield.

1951–52 Port Vale F.C. season: The 1951–52 season was Port Vale's 40th season of football in the Football League, and their seventh full season in the Third Division South.  Manager Ivor Powell did not last long, and was replaced by Freddie Steele in December.  Steele would later prove to be one of the club's greatest and longest serving managers.  He started early, taking a club bottom of the league at Christmas to a thirteenth-place finish.  He achieved this without making any major signings, rather he managed the players he had in a better way than Powell.

Stan Steele: Stanley Frederick Steele (born 5 January 1937) is an English former footballer.  A half-back and inside-forward, he scored 97 goals in 370 league and cup games for Port Vale between 1955 and 1968.  His parents named him Stanley Frederick in honour of Stanley Matthews and Freddie Steele.

1962–63 Port Vale F.C. season: The 1962–63 season was Port Vale's 51st season of football in the Football League, and their fourth season in the Third Division.  An impressive season saw them finish in third position, one away from promotion.  However promotions for both their rivals Stoke City (second to first tier) and Crewe Alexandra (fourth to third tier) meant that Vale had a poor season in comparison.  The major talking point of the season was Norman Low's departure and Freddie Steele's return, which came as a shock to the fans.

1952–53 Port Vale F.C. season: The 1952–53 season was Port Vale's 41st season of football in the Football League, and their first season (fourth overall) back in the Third Division North, following their switch from the Third Division South.  Using an incredibly settled squad (only nineteen players were used all season), manager Freddie Steele led the Vale to a second-place finish, just a single point from the promotion spot.  Built upon an 'iron curtain defence', just 35 goals were conceded in 46 league games.  All this was achieved with pretty much the same bottom-placed team that Steele inherited in December 1951.

Jimmy Nicholl: James Michael Nicholl (born 28 February 1956) is a Canadian-born former Northern Ireland international footballer who played for several clubs, including Manchester United and Rangers.  He was mainly a right-back but could also play in other defensive roles.  Nicholl won a total of 73 international caps for Northern Ireland, scoring one goal.

Andy Smith (footballer, born 1980): Andrew William Smith (born 25 September 1980) is a former Northern Ireland international footballer.  He had a 16-year career playing professional and semi-professional football in Northern Ireland, England, Scotland, Belgium, and Portugal.  He also won 18 caps for Northern Ireland between 2003 and 2005 and one cap for the Northern Ireland B team in 2003.

David Kelly (association footballer): David Thomas Kelly (born 25 November 1965), also known by the nickname Ned Kelly, is a former Republic of Ireland international footballer who now works as joint-caretaker-manager at EFL League Two club Port Vale, alongside Chris Morgan.  He scored nine goals in 26 international games for the Republic of Ireland, and was a squad member for UEFA Euro 1988, the 1990 FIFA World Cup, and the 1994 FIFA World Cup.  A forward, he scored a total of 250 goals in 744 league and cup appearances in a 19-year career in professional football.

1956–57 Port Vale F.C. season: The 1956–57 season was Port Vale's 45th season of football in the Football League, and their third successive season (thirty-second overall) in the Second Division.  An unmitigated disaster from start to finish, they were relegated in bottom place with just 22 points from 42 games.  It was the end of an era, as the reputation of 'the Steele Curtain' had taken a severe blow, and its architect Freddie Steele left the club in January.  The season was considered to be one where the old guard 'cracked', and thus many loyal servants of the club were let go in the summer of 1957, including Ray King, Reg Potts, Stan Turner, Tommy Cheadle, and Stan Smith.

Billy Bingham: William Laurence Bingham, MBE (born 5 August 1931) is a former Northern Ireland international footballer and football manager, who now works as a scout for English Championship side Burnley.
