Former Premier League referee Mark Clattenburg has stepped into the debate surrounding one of Celtic’s disallowed goals against St Mirren over the weekend.

The Bhoys produced a hard-fought comeback victory against the in-form Buddies, with Liam Scales and Yang Hyun-jun finding the net.
Yet Matin O’Neill’s men left the pitch feeling they could easily have added two more goals on another afternoon.
Two Goals Ruled Out in Tight Contest
Both Shim Mheuka and Camilo Duran saw efforts chalked off during the match.
The decisions were extremely close, but Celtic supporters reserved their strongest frustration for Duran’s disallowed strike.
That moment arrived before the home side had scored a legitimate goal, heightening the sense of injustice among the fans.
The Replay That Sparked Outrage
The source of the anger became clear when the television replay was shown.
To the naked eye the forward looked to be level, if not fractionally onside.
Thousands of supporters immediately took to social media to demand answers from the officials.
Clattenburg Offers His Expert View
Mark Clattenburg believes the match officials had access to a tighter camera angle that justified the offside call.
He explained the technical requirements that must be met for such a decision.
“Celtic’s offside looks tight to the naked eye, and the player must be ahead of the ball and ahead of the second most rear defender for the decision to be given,” Clattenburg said.
No Room for Doubt Under Current Rules
“It’s a very tight one as he is ahead of the ball and it looks like a foot is ahead of the defender. We have to trust the match officials in this case, especially when it’s so tight.”
Clattenburg was unequivocal about the nature of the law.
“Offside is factual, and therefore 1cm is offside, and there is no margin to give the benefit of the doubt to the attacker.”
Celtic’s Response on the Pitch
Despite the setbacks, Celtic refused to let the decisions define their afternoon.
Liam Scales rose highest to restore parity and shift the momentum firmly in the home side’s favour.
Yang Hyun-jun then provided the decisive finish that secured all three points against a dangerous St Mirren side.
Recent Form Adds Context to the Result
Celtic entered the fixture in solid domestic form, looking to maintain pressure at the top of the Scottish Premiership table.
St Mirren arrived with genuine confidence after a strong run of results that had lifted them into the upper half of the standings.
The visitors’ organisation made the comeback all the more impressive once the early disallowed efforts were set aside.
Tactical Battle Unfolds
Matin O’Neill’s side controlled large periods of possession and forced St Mirren into deep defensive blocks.
The disallowed goals came from moments of sharp combination play that briefly unlocked the Buddies’ shape.
Celtic’s willingness to recycle possession and switch the point of attack eventually wore the visitors down.
Defensive Resilience Proves Key
At the other end, Celtic’s back line remained compact after the early scares.
Scales’ goal was the product of a well-worked set-piece routine that St Mirren struggled to contain.
Yang’s winner showcased the clinical edge that has underpinned Celtic’s recent league performances.
Fan Frustration Remains High
Even after the final whistle, large sections of the Celtic support continued to discuss the Duran decision.
Many argued that the naked-eye view should have been enough to allow the goal.
Others pointed out that modern technology has removed the benefit of the doubt that once existed for attacking players.
Social Media Reaction Intensifies
Online discussion quickly focused on the centimetre-level margins that decided the call.
Supporters questioned whether the spirit of the game is being preserved when celebrations are cut short by such fine lines.
A significant number called for clearer communication from officials when tight offside decisions are made.
The Wider Debate on Offside Technology
Clattenburg’s comments highlight a growing conversation within the game about the current application of the offside law.
The former referee accepted that the decision was correct under existing rules, yet acknowledged how frustrating such moments can feel.
He noted that future changes may introduce a degree of tolerance, but for now the letter of the law must be followed.
Margins That Define Matches
Football has reached a point where the difference between a goal and a free-kick can be measured in millimetres.
That reality leaves players, managers and fans constantly second-guessing what they have just witnessed.
Celtic’s ability to overcome the setback and still claim victory prevented the decision from becoming a season-defining controversy.
Looking Ahead for Both Sides
Celtic will now turn their attention to the next fixture knowing they found a way to win despite the early frustration.
The result keeps them firmly in the hunt at the summit of the league table.
St Mirren, meanwhile, can take encouragement from a disciplined display that pushed the title contenders all the way.
Tactical Lessons from the Afternoon
Matin O’Neill’s men demonstrated patience when the early chances were ruled out.
Their continued pressure eventually forced the opening that Scales exploited.
Yang’s late contribution underlined the depth available in the Celtic attacking ranks.
Protecting the Spirit of the Game
Many observers share the hope that a more common-sense approach will eventually be introduced.
The aim would be to protect the excitement of goal celebrations rather than forcing fans to wait for confirmation.
Until such changes arrive, the current factual interpretation of offside will continue to produce these razor-thin calls.
A Result That Ultimately Matters Most
In the end Celtic found the net twice through legitimate means and left with the three points.
That outcome will matter far more in the long run than the debate over Duran’s disallowed effort.
Still, the discussion around the decision is unlikely to disappear quickly among the Celtic support.
Clattenburg’s measured analysis provides the clearest explanation available so far.
He insists the officials will have seen an angle that confirmed the offside by the smallest of margins.
For now the rules remain absolute, and 1cm continues to be enough to deny a goal.
Celtic’s comeback ensured the afternoon ended in celebration rather than lasting bitterness.
Yet the episode serves as another reminder of how technology and law combine to shape modern football.
Supporters will keep hoping for a future framework that restores a little more joy to the moment a ball hits the net.
