For generations of Celtic supporters, the roar of the Old Firm has always felt eternal. Managers come and go, legends rise and fall, but somehow the rivalry between Celtic F.C. and Rangers F.C. never loses its fire.
But this weekend feels different.
At 74 years old, Martin O’Neill is once again standing on the touchline for Celtic in the biggest fixture in Scottish football. And according to reports surrounding the club, this may be his final Old Firm clash before stepping away from management for good.
For many fans, that possibility is difficult to accept.
O’Neill is not just another manager in Celtic history. He is one of the men who reshaped the modern identity of the club. When he first arrived in 2000, Celtic were desperately trying to stop Rangers’ dominance. Within months, O’Neill transformed belief into glory. His first Old Firm game ended in that unforgettable 6-2 demolition of Rangers, a result still spoken about like folklore around Parkhead.
That era delivered trophies, unforgettable European nights, and a connection between manager and supporters that few coaches ever achieve. Under O’Neill, Celtic reached the UEFA Cup Final in Seville and restored pride to a fanbase craving greatness again.
Now, more than two decades later, he is back in the dugout one more time.
His return initially felt temporary. After chaos behind the scenes and managerial instability, Celtic turned back to the man supporters trusted most. O’Neill answered the call again, guiding the club back into the title race and restoring calm around the dressing room.
But time waits for nobody.
Reports this week suggest O’Neill intends to hand the job over to a younger successor at the end of the season. While he remains deeply passionate about football, those close to the situation believe the emotional and physical demands of elite management are becoming impossible to ignore.
And that is what makes this final Old Firm occasion so emotional.
Because O’Neill still loves these matches.
Speaking recently, he admitted the fixture remains “something special” even after everything he has experienced in football. You can still see it in his face during the anthems, the tension on the sideline, the celebrations after dramatic goals. The fire never truly disappeared.
That is why supporters are struggling with the idea that Sunday could be the last time they see him leading Celtic into battle against Rangers.
Football rarely gives fairytale endings. But if there was ever a manager who deserved one final unforgettable Old Firm victory, it might be Martin O’Neill.Because long after the trophies fade and the statistics are forgotten, Celtic fans will remember something more important.He made them believe again.
