Celtic’s humiliating Old Firm defeat at Ibrox has reportedly been followed by an explosive dressing-room fallout, with tensions inside the squad said to have boiled over after the players were left to confront the reality of their 3-0 defeat to Rangers.
The scale of the result was already bad enough.
But behind closed doors, the frustration is understood to have gone a step further.
According to claims circulating around the Celtic camp, two senior first-team players became embroiled in a heated confrontation over the performance, with the argument reportedly centring on the same issues that captain Callum McGregor publicly raised afterwards: work rate, responsibility and the failure to respond once Rangers took control.
The incident is said to have begun as a disagreement over what went wrong at Ibrox before becoming increasingly heated, with both players allegedly exchanging strong words in front of teammates.
And with Celtic now facing another Old Firm meeting at Celtic Park next weekend, the timing could hardly be more uncomfortable.
McGregor had already made his feelings clear
There was little doubt from McGregor’s post-match interview that the Celtic captain was furious.
Rather than hide behind the result or suggest Rangers had simply produced an exceptional performance, McGregor openly questioned Celtic’s mentality, collective effort and willingness to work for one another.
The midfielder admitted that once Celtic fell behind, they “never looked like recovering”.
He also criticised the way Celtic repeatedly surrendered possession, describing their play as careless and slack even when they were not under significant pressure.
But it was his assessment of the team’s overall character that really stood out.
McGregor said Celtic had looked like “a team of individuals” while Rangers had looked like a proper team.
That was an extraordinary admission from the captain.
And it is precisely why the reported confrontation between two players would be so significant if accurate.
The argument allegedly centred on responsibility for the collapse — particularly the perception that some players failed to do enough once Rangers began to take complete control of the match.
The dressing-room tensions reportedly boiled over
The details of what happened behind closed doors remain unconfirmed, and neither Celtic nor the players involved have publicly addressed the alleged confrontation.
However, the claims suggest that frustration did not simply disappear once the final whistle went.
Two senior players are reportedly said to have clashed over the team’s performance and attitude.
One was allegedly critical of the other’s contribution and leadership as Celtic struggled to respond to Rangers.
The response, however, was reportedly just as blunt.
What had started as an argument about the game apparently became a much more personal exchange, with teammates eventually stepping in to prevent the situation from escalating.
It is understood that the confrontation did not become physical.
Nevertheless, the fact that teammates and club staff reportedly had to intervene would underline just how raw emotions were inside the Celtic camp.
And there was plenty for the players to be angry about.
Rangers had controlled the game, Celtic had struggled to create a sustained response and the visitors’ performance deteriorated as the afternoon progressed.
McGregor’s words make the fallout even more revealing
Perhaps the most striking element is how closely the reported argument mirrors the concerns McGregor himself raised publicly.
The captain effectively challenged his teammates to accept that Celtic had failed collectively.
He pointed towards poor passing, a lack of running and players becoming disconnected from one another.
“You can’t defend with six players, it’s impossible,” McGregor said.
That comment provides a revealing insight into what appears to have frustrated him most.
For Celtic, the problem was not simply that Rangers were better.
It was that too many players appeared to stop functioning as a collective once the game turned against them.
McGregor’s criticism therefore went beyond tactics.
It was about responsibility.
Every Celtic player had to be prepared to run when the team lost possession. Every player had to be prepared to suffer for the man beside him.
Instead, according to their captain, Rangers looked like a team while Celtic looked like a collection of individuals.
That is the kind of criticism that can linger long after the final whistle.
Another Old Firm clash is already waiting
The timing makes the situation even more significant.
Celtic do not have the luxury of putting the Rangers defeat behind them for several months.
Another meeting between the two clubs is already on the horizon, this time at Celtic Park.
That gives Martin O’Neill an immediate problem to solve.
The manager will need to restore confidence, repair whatever tension exists within the dressing room and convince his players that the Ibrox performance was an unacceptable outlier rather than a sign of deeper problems.
The last thing Celtic need is for disagreements between teammates to become a distraction.
At the same time, some level of confrontation can be exactly what a hurting dressing room needs.
Players have to be willing to challenge one another.
The danger comes when that frustration turns into division.
Celtic need a response — and quickly
For all the anger surrounding the Ibrox defeat, the most important question is what happens next.
McGregor himself made it clear that Celtic cannot simply talk their way out of the situation.
They have to respond on the pitch.
The captain’s message was essentially that Celtic need to rediscover the collective identity that has been missing in their biggest matches.
If the reported dressing-room confrontation did take place, it may ultimately prove to be either a warning sign or a turning point.
It could deepen the divisions exposed at Ibrox.
Or it could force the players to confront problems that had previously been left unspoken.
For now, the identities of the two players allegedly involved remain private.
But one thing is already clear: Celtic’s 3-0 defeat was not simply another Old Firm loss.
It has left serious questions about the team’s togetherness, character and ability to respond under pressure.
And with Rangers waiting again next weekend, Celtic will not have long to provide the answer.
