Martin O’Neill Signs New Deal with Celtic for 2026–27

Martin O’Neill has signed a new one-year deal to stay on as Celtic manager, rewarded for dragging the club from chaos back to the summit of Scottish football.

The Derry native, who had initially stepped away when Wilfried Nancy was appointed on a permanent basis midway through last season, returned to the dugout after the Frenchman was sacked just 33 days into the job. From there, Celtic’s season flipped on its head.

What had looked like a campaign drifting off course became a charge. O’Neill steadied the dressing room, tightened the structure on the pitch and, crucially, restored belief in a squad that had been stumbling. The turnaround reached its peak on a breathless final day at Parkhead, where Celtic snatched the league title against Hearts in a winner-takes-all showdown that will live long in the stands’ memory.

That victory completed a League and Cup double for the defending champions, a feat that underlined why the board moved quickly to secure O’Neill’s future for at least another year. Stability, after months of uncertainty, suddenly has a face again.

The decision comes against the backdrop of heavy speculation linking Robbie Keane with the role. The Republic of Ireland’s record caps holder and all-time leading goalscorer, Keane has been out of work since leaving Ferencvaros and was widely touted as a serious contender.

Keane’s connection with Celtic is real and fondly remembered on the pitch. His prolific loan spell at Celtic Park in 2010 briefly lit up the club’s attack, and his managerial career has already brought league titles in Israel and Hungary.

This time, though, the door did not open. Some Celtic supporters had voiced strong opposition to Keane’s potential appointment, focusing on his previous association with Maccabi Tel Aviv. A statement against the move was said to have been signed by “dozens” of Celtic supporters’ groups, a clear sign that his candidacy would have been divisive.

Instead, the club have turned back to the man who has already proved he can navigate a crisis in Glasgow’s east end. O’Neill, battle-tested and now freshly reinstalled, goes into 2026–27 with a double in his pocket, a title to defend, and a fanbase expecting this revival to be a launchpad rather than a last act.
