Martin O'Neill is poised to take a hard look at his position as Celtic manager after the team fell 1-0 to Rangers at Parkhead, intensifying speculation about his tenure. The Light Blues had just celebrated a convincing 3-0 League Cup triumph over the Hoops at Ibrox the previous Sunday, and in the Scottish Premiership rematch a first‑half goal from Ryan Naderi had lifted Derek McInnes' Rangers to within two points of Celtic at the top of the table heading into the international break. This was O'Neill's second spell as the permanent boss, following two interim appointments earlier in the season, and the pressure on him had already been mounting after a disappointing 3-1 loss to Ferencvaros at Celtic Park on Thursday night.

The 74‑year‑old manager, after another sub‑par performance, admitted he needed a period of self‑reflection. "I will genuinely reflect and see," the Northern Irishman said. "The question is whether I can still help the team. A manager is supposed to be able to do that, so I will think about it this week." He went on to acknowledge that age can be a factor when results slip.

"Every time something goes wrong, you start to wonder if age is playing 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," he added. O'Neill said he would review the recent games and discuss the situation with the board, hinting that the club might also want to talk to him. "I’ll try to get a couple of days away and see how it goes," he said, indicating a short break could help him gain perspective.

When asked what he would do if his reflection concluded that he could no longer improve the squad, O'Neill replied, "By that time, I promise you, I’ll let you know. I don’t know yet.

I’ll have a look." He also addressed the growing negativity among Celtic supporters, acknowledging their frustration. "They are absolutely entitled to be upset," O'Neill said. "I’m not immune to criticism – far from it.

It’s natural to ask, ‘Can you turn this around? Can you change the whole thing?’" He reminded everyone that Celtic were still two points clear at the top, urging a broader view of the season.

"We are in a big fight with Rangers and Hearts, who are still very much in the mix. It’s a long season ahead," he noted.

"I’ve been questioned before about my managerial time, so I will reflect and see what the next steps are." Former Celtic manager Neil Lennon weighed in on Sky Sports, commenting on O'Neill's tactical adjustments. "He changed the formation and made four changes mid‑week, trying to find a formula for fluidity," Lennon observed.

"Rangers were the superior side, not just physically but in footballing terms. They executed their game plan perfectly.

Celtic were better in the first half, but not brilliant, and fell apart in the second half – disjointed, outworked, and battered." Lennon added that the upcoming international break could be a useful reset for the squad, despite many players being away on national duty. "The last three performances in a week have been very poor, so a total reset is needed," he said.

Sky Sports analyst Chris Sutton echoed similar concerns. "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," Sutton remarked. "I can’t recall a Celtic side being so thoroughly outplayed at Celtic Park by Rangers. It looked like Celtic were improvising, while Rangers were better in every department." Sutton summed up the situation: "Celtic have big problems.

Being smashed by Rangers is a serious concern." The defeat has sparked a broader conversation about O'Neill's future and whether the club will seek a new direction or give the veteran manager more time to turn things around. With the league still very much open and Celtic only a narrow margin ahead, the next few weeks will be crucial.

The manager’s self‑assessment, the board’s response, and the fans’ patience will all play a part in shaping the next chapter for Celtic. If O'Neill decides to step aside, the club will need to identify a successor capable of restoring the team’s dominance. If he stays, he will have to implement swift tactical changes, boost player confidence, and perhaps bring in fresh ideas to halt the slide.

Either way, the Light Blues face a pivotal moment in their season, and the outcome will likely define the trajectory of both O'Neill’s career and Celtic’s ambitions for the remainder of the campaign.
