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 comes on the heels of a dominant 3-0 League Cup victory over the same opponents at Ibrox last week, and it leaves Celtic perched just two points clear of Rangers at the top of the Scottish Premiership heading into the international break. In his second permanent stint at Celtic – following two interim spells earlier in the season – O'Neill entered the match under mounting pressure.

The pressure had intensified after a 3-1 loss to Ferencváros in the Europa League on Thursday night, a result that left many fans and pundits questioning the direction of the team. Following the Rangers defeat, the 74‑year‑old manager admitted that he would spend the coming days in self‑reflection.

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

A manager’s job is to improve the team, and I will consider that this week." He went on to acknowledge that age might be a factor in his performance. "Every time things don’t go well, you start to think about age," O'Neill remarked. "In two years I’ll be 110, so perhaps it’s time to think about wrapping things up. I will review the games, talk to the board, and maybe take a few days away to gain perspective." When pressed about what he would do if his self‑assessment concluded that he could not lift the side, O'Neill answered cautiously: "If I come to that conclusion, I will let everyone know.

I don’t have a definitive answer right now, but I will look at it." Addressing the growing negativity among Celtic supporters, O'Neill said he understood their frustration. "The fans are absolutely entitled to be upset," he said.

"I’m not immune to criticism – far from it. It’s natural for people to ask whether I can turn this around, whether I can change the situation. We are two points clear, but the bigger picture is that we are in a fierce battle with Rangers and Hearts, both of whom are still very much in contention." He emphasized the length of the season ahead, noting that this is not the first time his tenure has been under scrutiny. "It’s a long campaign, and I have faced questions about my managerial future before.

I will reflect, I will speak to the board, and I will see what the next steps are," O'Neill concluded. Former Celtic boss Neil Lennon weighed in on Sky Sports, offering his own analysis of the performance.

"Martin changed the formation and made four changes mid‑week, trying to find a formula that gives the team fluidity," Lennon said. "Rangers were superior in every aspect – physically, in running, and in footballing quality. They played a complete game, while Celtic were only decent in the first half and fell apart in the second.

The second half was disjointed, outworked and battered." Lennon added that the international break could serve as a useful reset for Celtic. "Many of the players will be away on international duty, but the team needs a total reset because the last three performances in a week have been very poor," he warned. Sky Sports analyst Chris Sutton echoed similar concerns.

"Knowing Martin, he’ll be very worried after that result. I don’t want to disagree with him, but it wasn’t a close game – there was a massive gulf between the sides," Sutton said. "I can’t recall a Celtic team being so thoroughly outplayed at Celtic Park by Rangers.

Celtic seemed to be improvising, while Rangers were better in every department." Sutton summed up the situation succinctly: "Celtic have big problems. Being smashed by Rangers is a serious concern and needs to be addressed immediately." The defeat has sparked a broader conversation about the future direction of Celtic. While the club remains within touching distance of the league title, the inconsistency displayed in recent weeks – a dominant cup win, a heavy European loss, and a narrow league defeat – has left supporters and the board questioning whether a change in leadership is required to secure sustained success.

O'Neill’s forthcoming reflection period will likely involve detailed discussions with the Celtic board, an assessment of the squad’s depth, and a strategic review of tactics and player development. Whether he decides to stay on and attempt to steer the club back to form, or steps aside for a new appointment, the outcome will shape Celtic’s trajectory for the remainder of the season and beyond. In the meantime, the team will head into the international break with a chance to regroup, recover, and perhaps rediscover the confidence that propelled them to a 3-0 cup victory just days earlier. The break could also provide an opportunity for injured players to heal and for the coaching staff to fine‑tune their approach ahead of the crucial fixtures that await upon the league’s resumption.
