Celtic’s extraordinary Champions League collapse against LASK has taken another dramatic turn following reports of a possible UEFA investigation into the controversial circumstances surrounding the tie.
The Scottish champions suffered one of the most painful European nights in their recent history after throwing away a commanding advantage against the Austrian side.
Celtic travelled to Austria holding a 3-0 advantage from the first leg at Celtic Park. Their position appeared even stronger when captain Callum McGregor scored in the second leg to make it 1-0 on the night and 4-0 on aggregate.
However, what followed stunned Celtic supporters.
LASK produced an incredible comeback, scoring five times to overturn the deficit and eventually win the second leg 5-1 after extra time. The Austrian club therefore progressed 5-4 on aggregate. UEFA’s official match record confirms LASK’s qualification following the dramatic turnaround.
The result has generated widespread debate, particularly because Celtic had appeared to have complete control of the tie before their dramatic collapse.
Replay claims create fresh uncertainty
Reports circulating online have suggested that UEFA could investigate issues surrounding the match, with some claims even pointing towards the possibility of the tie being replayed.
However, there is an important distinction between an investigation or complaint being discussed and UEFA actually ordering a replay.
At present, UEFA’s official competition information continues to list LASK as the team progressing from the play-off tie. UEFA’s own records show the second leg as LASK 5-1 Celtic, with the Austrian side winning 5-4 on aggregate.
That means Celtic supporters should be cautious about claims that a replay has already been approved.
Celtic’s collapse shocked European football
The scale of Celtic’s collapse has made the tie one of the biggest talking points in European football.
Having won the first meeting 3-0, Celtic were four goals ahead on aggregate after McGregor’s second-leg opener. Instead of managing the advantage, Martin O’Neill’s side conceded repeatedly as LASK gained belief.
Samuel Adeniran was central to the comeback, while Robert Ljubicic and other LASK players helped turn the contest completely on its head. Adeniran ultimately scored the decisive extra-time goal that completed one of the most remarkable comebacks in the competition.
UEFA’s official head-to-head record now lists the two clubs level at one win apiece, with LASK having scored five goals against Celtic’s four across the two meetings.
Martin O’Neill accepts responsibility
The defeat has also placed huge pressure on Celtic manager Martin O’Neill.
The experienced manager admitted after the collapse that the result was extremely painful, while Celtic captain McGregor also accepted that the team had failed to perform when it mattered most.
Celtic’s elimination means they will not participate in the 2026/27 Champions League league phase. UEFA’s competition format states that teams defeated in the play-offs move into the Europa League league phase instead.
For Celtic, that represents a significant sporting and financial setback.
What happens next?
The biggest question surrounding the developing story is whether any formal UEFA disciplinary or regulatory process could alter the outcome.
For now, there is no verified UEFA confirmation that Celtic and LASK will replay the match. UEFA’s official records continue to recognise LASK as the winner of the tie.
Therefore, unless UEFA publishes a formal decision changing the result, LASK remain the team that progressed to the Champions League league phase.
Nevertheless, the reported investigation claims are likely to keep the controversy alive among Celtic supporters, particularly after a match that appeared impossible to lose when the Scottish side held a four-goal aggregate advantage.
What began as a routine Champions League qualification mission has consequently become one of the most extraordinary European collapses in Celtic’s history — and any genuine UEFA decision could add another remarkable chapter to the story.
