Martin O'Neill is poised to take a hard look at his position as Celtic manager after the side suffered a 1-0 loss to Rangers at Parkhead. The defeat adds to the scrutiny surrounding his tenure, especially following a 3-0 League Cup triumph over the same opponents at Ibrox last week.

In the league rematch, Ryan Naderi’s first‑half goal had put Derek McInnes' Rangers within two points of Celtic at the top of the table heading into the international break. This is O'Neill’s second spell as the club’s permanent head coach, after two interim appointments earlier in the season. The pressure on the 74‑year‑old intensified after Celtic were beaten 3-1 by Ferencváros at home on Thursday night, a result that left fans and pundits questioning the direction of the team. In the aftermath of the Rangers loss, O'Neill admitted he was entering a period of self‑reflection.

"I will genuinely reflect and see," the Northern Irishman said. "The question is whether I can still add value to the squad.

A manager’s job is to improve the team, and I will examine that this week." He went on to acknowledge the inevitable impact of age on performance. "Every time things go wrong, you start to wonder if age is a factor.

I’ll be 110 in two years, so perhaps it’s time to consider wrapping things up," he joked, but the underlying tone was serious. O'Neill said he would discuss the situation with the board, take a few days away from the daily grind, and reassess his future.

When pressed about what he would do if his reflection concluded that he could no longer lift the side, O'Neill replied, "If I come to that conclusion, I will let everyone know. I don’t have an answer right now; I need to look at it." Addressing the growing negativity among Celtic supporters, O'Neill said, "The fans are absolutely entitled to be critical. I mentioned that on Friday – they have a right to voice their concerns.

I am not immune to criticism; in fact, I welcome it. The big question is whether I can turn things around." He reminded everyone that Celtic still sit two points clear at the top, urging a broader perspective. "We are still in a tight race with Rangers and Hearts, who are still very much in contention.

The season is long, and this is not the first time my managerial credentials have been questioned. I will reflect, assess the bigger picture, and decide the next steps." Former Celtic boss Neil Lennon weighed in on Sky Sports, noting O'Neill’s attempts to tweak tactics. "He changed formation and made four alterations midweek, trying to find a formula that gives the team fluidity," Lennon said.

"Rangers were the superior side, not just physically but technically. They executed their game plan perfectly. Celtic were decent in the first half but fell apart after the break – disjointed, outworked, and battered." Lennon added that the upcoming international break could be a useful reset for Celtic.

"Many of the players will be away on international duty, but the team needs a complete overhaul of mindset because the last three performances in a week have been sub‑par." Sky Sports analyst Chris Sutton echoed similar concerns. "Knowing Martin, he’ll be deeply worried.

I don’t want to disagree with him, but the game was not close – there was a massive gulf between the sides. I can’t recall a Celtic side being so outclassed at Celtic Park by Rangers. It looked like Celtic were improvising, while Rangers were superior in every department." Sutton concluded, "Celtic have serious issues to address.

Being thrashed by Rangers is a worrying sign and needs immediate attention." The defeat, combined with the earlier loss to Ferencváros, has sparked a broader debate about O'Neill’s long‑term suitability. Some argue that his experience and past successes could still be leveraged, while others suggest the club may need fresh ideas and a new direction.

The board’s upcoming meeting with O'Neill will likely determine whether he remains at the helm or steps aside for a successor. Regardless of the outcome, the immediate priority for Celtic is to regroup during the international break, address tactical deficiencies, and restore confidence among a fan base that feels increasingly restless. The next few weeks will be crucial in shaping the narrative for the rest of the season and possibly the future of Martin O'Neill at Celtic.
