Martin O’Neill at Celtic

Martin O’Neill took charge of Celtic in 2000 and quickly turned the club into a dominant force in Scottish football. His side won a domestic treble in his very first season in charge. Meanwhile, Celtic reached the 2003 UEFA Cup final, a rare run in Celtic’s European history. O’Neill built that team around discipline and momentum rather than individual stars.

Career Before Celtic

O’Neill began as a player with Distillery before Nottingham Forest signed him. He later turned out for Norwich City, Manchester City and Notts County. He also won senior caps for Northern Ireland during his playing career. As a manager, he first took charge of Wycombe Wanderers, then Norwich City and Leicester City. Leicester City won two League Cups under his management. Indeed, that success convinced Celtic to appoint him in 2000.
