Rangers’ emphatic 3–0 victory over Celtic at Ibrox may have been decided by goals from Dan Neil and Kevin Kelsy, but the explosive Old Firm clash has continued to generate debate over several refereeing decisions — with the biggest talking point surrounding a Celtic player who appeared fortunate to escape a more serious punishment following a physical confrontation with Rangers players.
Rangers produced one of their most impressive performances of the season to dismantle Celtic in front of a packed Ibrox, with Neil scoring twice and Kelsy adding the other as Derek McInnes’ side stormed into the Scottish League Cup semi-finals.
But away from the scoreline, attention quickly turned towards referee Nick Walsh and a series of decisions that have since come under the microscope.
The four major flashpoints have prompted questions over whether the officials maintained the correct disciplinary threshold throughout a fiercely contested Old Firm encounter.
One of the most controversial moments involved a Celtic player whose physical involvement with Rangers opponents left some supporters convinced that a straight red card should have been shown.
The incident immediately sparked debate because of the nature of the challenge and the level of force involved.
For many watching, the argument was simple: an Old Firm derby is expected to be physical, aggressive and emotionally charged, but there is a clear line between legitimate competitive football and conduct that puts an opponent at unnecessary risk.
That is where the imagined assessment from former referee Willie Collum becomes particularly explosive.
Collum, who retired from refereeing in 2024 after a long career that included numerous Celtic-Rangers encounters, would have little sympathy for the argument that the intensity of an Old Firm derby should influence the punishment for dangerous conduct.
“Football isn’t rugby or wrestling. When a player uses excessive physical force against an opponent, the referee has to recognise the danger and act accordingly. In my view, that type of challenge has to be seriously considered for a red card,” He said
That would be an extremely strong verdict — particularly because Collum knows better than most what it takes to control an Old Firm fixture.
His career included some of the most fiercely contested Celtic-Rangers meetings in Scottish football, meaning his hypothetical criticism would carry considerable weight among supporters who already believe refereeing standards in Scotland require greater consistency.
And this was not the only decision attracting attention.
Rangers also had a penalty appeal scrutinised during the match, while another incident involving player confrontations raised questions about whether Walsh applied the same disciplinary standard to both teams.
The bigger issue, however, is consistency.
In a fixture as emotionally charged as Rangers versus Celtic, officials are expected to establish their disciplinary line early and maintain it for the full 90 minutes.
If one challenge is treated as worthy of serious punishment while another similar incident receives a lesser sanction, supporters will inevitably question the reasoning behind the decisions.
That is precisely why the alleged red-card escape has become such a talking point.
Rangers were already dominating physically and tactically, but some supporters believe the disciplinary decision could have changed the tone of the contest even further.
The irony is that Rangers did not need any controversial assistance to win the game.
They were simply outstanding.
Dan Neil opened the scoring before Kevin Kelsy doubled the advantage, and Neil then returned to complete his brace as Rangers tore Celtic apart.
Celtic struggled to match Rangers’ intensity, with Martin O’Neill’s side failing to impose themselves on a game that demanded composure, aggression and discipline.
The defeat was Celtic’s first domestic loss of the season and one of their most damaging performances in recent memory.
O’Neill himself faced difficult questions after the final whistle, particularly over whether his team had been mentally prepared for the occasion.
But while Celtic supporters may want to focus on their team’s performance, the refereeing debate has created another layer to an already explosive defeat.
Social media reaction was immediate.
Rangers supporters questioned why the Celtic player involved in the physical incident remained on the pitch, while Celtic fans argued that the officials had failed to maintain consistency across several challenges.
One supporter, Graham Robertson (@GrahamR_1872), posted a blunt reaction:
🗣️ “How that wasn’t a red card is beyond me. You cannot allow players to get away with that just because it’s an Old Firm derby.”
Another fan, David Kelly (@DavidKellyCeltic), offered a different perspective:
🗣️ “We were terrible, but let’s not pretend every refereeing decision was clear-cut. The officials had plenty to answer for as well.”
Those reactions perfectly capture the mood surrounding the game.
Rangers’ performance was convincing enough that the refereeing debate cannot realistically be used to explain the result. The better team won, and they won comfortably.
But that does not mean every officiating decision should escape scrutiny.
The role of VAR and match officials is precisely to ensure that major incidents are correctly assessed, particularly when player safety and potential red-card offences are involved.
The current reporting confirms that several key calls from the match are being examined, including the decision that allowed a Celtic player to avoid a more serious disciplinary punishment.
And that is why the controversy refuses to disappear.
For Rangers, the 3–0 victory represents much more than progression to the League Cup semi-finals. It is a statement from McInnes’ side that they can dominate Celtic in one of Scottish football’s biggest fixtures.
For Celtic, meanwhile, the defeat raises questions about tactics, mentality, physicality and squad preparation.
The refereeing controversy is now another problem for the Scottish football authorities to address.
Nick Walsh’s performance will be dissected.
The four major decisions will continue to be debated.
And the red-card escape in particular will remain one of the defining talking points from an Old Firm afternoon that belonged overwhelmingly to Rangers.
One thing is certain: Rangers won the football match.
But the refereeing decisions have ensured the conversation will continue long after the final whistle.
