About Martin O'Neill
Martin Hugh Michael O'Neill (born 1 March 1952) is a Northern Irish professional football manager and former player who played as a midfielder. He is the manager of Scottish Premiership club Celtic. After a brief early career in the Irish League, O'Neill moved to England where he spent most of his playing career with Nottingham Forest. He won the First Division title in 1977–78 and the European Cup twice, in 1979 and 1980. He was capped 64 times for the Northern Ireland national football team, and captained the side at the 1982 World Cup. At club level, O'Neill has managed Grantham Town, Wycombe Wanderers, Norwich City, Leicester City, Celtic, Aston Villa, Nottingham Forest and Sunderland. He guided Leicester City to the Football League Cup final three times, winning twice. As Celtic manager between 2000 and 2005, he led the club to seven trophies including three Scottish Premier League titles, and reached the 2003 UEFA Cup Final. After joining Aston Villa, he achieved three consecutive sixth-place finishes in the English Premier League, and guided them to the 2010 Football League Cup Final. He became Republic of Ireland manager in 2013 and led them to qualification for UEFA Euro 2016 where they reached the last 16 of the tournament. In October 2025, he returned to Celtic as interim manager following Brendan Rodgers' resignation. He departed in December after Wilfried Nancy was appointed permanent manager. After just 33 days, however, Nancy was dismissed and O'Neill was again appointed Celtic manager in January 2026. O'Neill ultimately guided Celtic to the Scottish Premiership title on the final day of the season. This was O'Neill's fourth Scottish title win. O'Neill then led Celtic to victory in the 2026 Scottish Cup Final, defeating Dunfermline Athletic 3–1 at Hampden Park to complete a domestic double. His brothers Gerry and Leo played for the club as well as being on the Derry senior team which won the 1958 Ulster Championship and reached that year's final of the All-Ireland SFC.
