Martin O'Neill is forced to take a hard look at his position as Celtic manager after the side suffered a 1-0 defeat to Rangers at Parkhead. The loss adds to the pressure on the Northern Irish coach, who has already seen his team enjoy a 3-0 League Cup triumph over the same opponents at Ibrox last week.

In the league encounter that followed, a first‑half goal from Ryan Naderi gave Derek McInnes' Rangers a narrow lead, leaving Celtic just two points behind the leaders as the Scottish Premiership entered the international break. This is O'Neill's second spell as Celtic's permanent boss, after stepping in twice as caretaker earlier in the season. The 74‑year‑old was already under fire after a 3-1 defeat to Ferencvaros at Celtic Park on Thursday night, and the recent home loss to Rangers has intensified calls for him to step aside.

In the aftermath of the match, O'Neill admitted he would enter a period of self‑reflection, saying, "I genuinely will reflect and see. It's a matter of whether I can help the team. The manager is supposed to be able to do that. I will look at that this week." He went on to acknowledge that age might be catching up with him, adding, "I think every single time something crops up and things don't go so well, age plays a part.

And, do you know what, they might be right. I'll be 110 in two years' time so it might be time to wrap it up." The manager said he would discuss the situation with the board and consider taking a short break to gain perspective. When asked what his next steps would be if his reflection concluded that he could no longer improve the squad, O'Neill replied, "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 supporters, O'Neill defended their right to be critical. "Well, I think they're absolutely entitled. I mentioned this to you on Friday, absolutely entitled to, of course.

And I'm not immune from criticism. Far from it. Absolutely and utterly far from it.

I think there's every reason to ask, 'can you turn this round? Can you change the whole thing?'" He reminded fans that Celtic still sit two points clear at the top, but warned that the season remains a marathon.

"We are, as I said, two points clear, so I have to kind of look at the bigger picture at this minute. But I knew that we were in a big, big fight anyway, with both ourselves, Rangers, and Hearts again, who are far from out of anything. It's a long season ahead.

It's not the first time I've been questioned about my managerial time. So, yeah, I'll have a look at it. I will reflect and see." Former Celtic manager Neil Lennon weighed in on Sky Sports, noting that O'Neill has been tinkering with his tactics.

"He's changed formation, he made four changes midweek. He's trying to find a recipe to get some fluidity.

Rangers were the far superior team, not just in physical attributes and running power, but football. They played all the football.

Celtic were a lot better than they have been in the first half, without being brilliant. But second half, totally disjointed, totally outplayed. Outworked, which is the worst thing you can label at a team.

Really disjointed, battered, actually battered. All the best players were in a blue shirt today. Celtic have a lot to ponder and a lot to work out. They've got an international break, which is probably coming at a good time for them.

I know a lot of them may be away playing for their countries but there needs to be a total reset because the last three performances in the space of a week have been very poor." Sky Sports analyst Chris Sutton echoed the sentiment, saying, "Knowing Martin, he'll be greatly concerned. I don't like to disagree with him but it wasn't a close game.

There was a massive gulf between the teams. I can't actually remember a Celtic team getting such a doing at Celtic Park from a Rangers team, which happened today. It looked like Celtic were making it up as they went along. Rangers were better in every department.

Celtic have got big problems. They were smashed by Rangers and that's a concern." The criticism extends beyond the pitch. Fans have taken to social media to question O'Neill's tactical acumen, his ability to motivate a squad that has shown flashes of brilliance but also moments of fragility, and whether his age is a limiting factor in an increasingly fast‑paced game. Some supporters argue that a fresh voice might reinvigorate the team, while others point to O'Neill's experience and past successes as reasons to give him more time.

Celtic's board, meanwhile, has remained relatively quiet, issuing only a brief statement after the loss, expressing confidence in the manager and emphasizing the club's long‑term vision. The upcoming international break offers a natural pause in the domestic schedule, and many pundits suggest it could be a pivotal moment for O'Neill to either re‑energise his side or consider stepping aside. If O'Neill decides to stay, he will likely need to address several key issues: restoring defensive solidity after a lapse that allowed Rangers to dominate the second half, improving the team's transition play to avoid the disjointedness highlighted by both Lennon and Sutton, and finding a way to extract consistent performances from his senior players who have struggled to impose their quality consistently.

Conversely, if he opts to leave, the club will face the challenge of appointing a successor capable of navigating a tight title race with Rangers and Hearts still in contention. The timing of any managerial change will be crucial, as Celtic would prefer to avoid a prolonged period of uncertainty during the decisive stages of the season. In summary, Martin O'Neill stands at a crossroads. The recent defeat has amplified doubts about his capacity to lead Celtic back to the summit, while his own admission that age may be catching up with him adds a personal dimension to the professional dilemma.

Whether he chooses to reflect, speak with the board, take a brief hiatus, or ultimately step down, the next few weeks will be decisive for both his career and Celtic's ambitions for the remainder of the campaign.
