Martin O'Neill is poised to take a hard look at his position as Celtic manager after the club suffered a 1-0 defeat to Rangers at Parkhead. The loss follows a 3-0 League Cup triumph over the same opponents at Ibrox and a tightly contested league match in which Ryan Naderi’s first‑half goal reduced the gap between Derek McInnes’ Rangers and Celtic to just two points before the international break began. Having been appointed permanently for a second spell after two interim stints last season, O'Neill entered the Rangers game already under a cloud of scrutiny.

The pressure intensified after a 3-1 home loss to Ferencvaros on Thursday night, a result that left many supporters questioning the direction of the club. In the aftermath of the latest defeat, the 74‑year‑old Northern Irishman admitted he would spend time reflecting on his future and the team's performance.

"I will genuinely reflect and see," O'Neill said in a post‑match interview. "The question is whether I can still help the squad.

A manager’s job is to make a difference, and I will examine that this week." He went on to acknowledge that age might be a factor in his decision‑making process. "Every time something goes wrong, you start to wonder if age is playing a part.

I’ll be 110 in two years’ time, so perhaps it’s time to think about wrapping things up," he added with a hint of humor. O'Neill said he would discuss the situation with the club’s board and possibly take a short break to gain perspective.

"I’ll speak to the board, maybe take a couple of days away and see how I feel," he explained. When pressed about what would happen if his self‑assessment concluded that he could no longer improve the team, he responded, "By then I’ll let you know. I don’t know yet; I’ll have to look at it." Addressing the growing negativity among Celtic fans, O'Neill acknowledged their frustration.

"They are absolutely entitled to be upset," he said. "I’m not immune to criticism – far from it. It’s natural for supporters to ask, ‘Can you turn this around?

Can you change things?’" He reminded everyone that Celtic still sat two points clear at the top of the table, urging a broader view of the season. "We’re in a big fight with Rangers, Hearts and others. It’s a long campaign, and this isn’t the first time my tenure has been questioned.

I’ll reflect, I’ll see what the future holds," he concluded. Former Celtic boss Neil Lennon weighed in on Sky Sports, noting O'Neill’s attempts to tweak the formation and make four changes at halftime. "He’s trying to find a recipe for fluidity," Lennon observed. "Rangers were the superior side, not just physically but tactically.

They dominated the game. Celtic were better in the first half, but the second half was disjointed, outworked and battered." Lennon stressed that the upcoming international break could be a useful reset for Celtic, despite many players being away on national duty. "They need a total reset because the last three performances in a week have been very poor," he said.

Sky Sports analyst Chris Sutton echoed similar concerns, saying, "Knowing Martin, he’ll be greatly concerned. It wasn’t a close game; there was a massive gulf between the teams. I can’t recall a Celtic side being so thoroughly outplayed at Celtic Park by Rangers." Sutton added, "Celtic seemed to be improvising as the match went on.

Rangers were better in every department. Celtic have big problems – being smashed by Rangers is a serious worry." The defeat has reignited speculation about O'Neill’s long‑term future at Celtic.

While the manager has previously demonstrated the ability to guide the club to domestic success, recent results have raised doubts among fans and pundits alike. The upcoming international break offers a chance for players to recover, for the coaching staff to reassess tactics, and for O'Neill to decide whether he can still deliver the standards expected at Celtic Park. If O'Neill chooses to step down, the club will need to identify a successor capable of restoring confidence and competing for titles.

Conversely, if he decides to stay, he will likely face heightened scrutiny and pressure to produce immediate improvements. Either way, the next few weeks will be pivotal for both O'Neill and Celtic as they navigate a critical juncture in the season.
