Martin O'Neill is set to take a hard look at his position as Celtic manager after the club’s 1-0 loss to Rangers at Parkhead, a result that has intensified scrutiny of his tenure. The defeat came just days after Celtic enjoyed a 3-0 victory over Rangers in the League Cup at Ibrox, and a first‑half goal from Ryan Naderi in the league fixture had briefly lifted the Hoops to within two points of the league leaders as the international break approached. This is O'Neill’s second spell as the permanent head coach, following two interim appointments earlier in the season. The pressure on him had already been mounting after a 3-1 home defeat to Ferencvaros in the Europa Conference League on Thursday night, a result that left many supporters and pundits questioning his tactics and squad selections.

In the wake of the latest setback, the 74‑year‑old manager spoke candidly about the need for personal reflection. "I genuinely will reflect and see," O'Neill said, emphasizing that a manager’s primary duty is to improve the team.

"It’s a matter of whether I can help the squad. I will look at that this week." He went on to acknowledge that age can be a factor in a coach’s effectiveness, adding a touch of humour to his self‑assessment: "I think every time something goes wrong, age plays a part. And you know what, they might be right. I’ll be 110 in two years’ time, so maybe it’s time to wrap it up." O'Neill said he would discuss the situation with the Celtic board and consider taking a short break to gain perspective.

"I will reflect on the games and speak to the board. You never know, they may want to talk to me. I’ll try to get a couple of days away and see how it goes," he explained.

When asked what his next steps might be if his reflection concluded that he could not turn the team around, O'Neill gave a non‑committal answer: "By that time, I will promise you, I’ll let you know. I don’t know. I’ll have a look." Addressing the growing negativity among Celtic fans, O'Neill acknowledged their frustration.

"They’re absolutely entitled to be upset," he said. "I’m not immune from criticism – far from it. There’s every reason to ask, ‘Can you turn this round?

Can you change the whole thing?’" He reminded everyone that Celtic still sat two points clear at the top of the table, urging a broader view of the season ahead. "We’re in a big fight with Rangers and Hearts, who are still very much in the mix.

It’s a long season. This isn’t the first time I’ve been questioned about my managerial time. I’ll reflect and see," O'Neill concluded. Former Celtic boss Neil Lennon weighed in on Sky Sports, noting O'Neill’s recent tactical tweaks.

"He changed formation and made four changes mid‑week, trying to find a recipe for fluidity," Lennon said. He praised Rangers for being superior not just physically but technically, describing Celtic’s second‑half performance as "totally disjointed, outworked and battered." Lennon suggested the upcoming international break could serve as a reset for the squad, despite many players being away on national duty.

Sky Sports analyst Chris Sutton echoed the criticism, saying he expected O'Neill to be deeply concerned. "It wasn’t a close game. There was a massive gulf between the teams," Sutton remarked, adding that he could not recall a Celtic side being so thoroughly outplayed at Celtic Park by Rangers.

He warned that the defeat highlighted “big problems” for the Hoops. The loss has sparked a broader conversation about O'Neill’s future. While some fans call for immediate change, others point to the club’s recent cup success and the narrow margin at the top of the league as reasons to give him more time.

The board’s next move could involve a formal review of O'Neill’s contract, a meeting with senior club officials, or possibly a brief sabbatical for the manager to reassess his approach. Celtic’s upcoming fixtures will be crucial.

With the league season still in its early stages and the Scottish Cup looming, the team must quickly address defensive frailties and find a way to translate their attacking potential into consistent results. Whether O'Neill can adapt his tactics, reinvigorate the squad, and restore confidence among the supporters will determine if his tenure at Celtic continues or comes to an end. In the meantime, the club’s fans remain divided.

Some are prepared to stand by the manager, hoping that the next few games will showcase a turnaround, while others argue that a fresh voice may be needed to steer Celtic back to the heights they expect. The coming weeks will reveal whether O'Neill’s period of reflection leads to renewed vigor on the touchline or signals the final chapter of his Celtic saga.
