Lyon president Jean-Michel Aulas has blasted VAR by insisting the technology was not used successfully in their Champions League
defeat at Barcelona
Aulas' grievance comes after claims emerged that UEFA had intimated that there were technical problems with VAR during the review of Barcelona's penalty in the first half of Wednesday's game.
Barcelona were awarded a contentious penalty with the scores 0-0 after Jason Denayer appeared to catch Luis Suarez
's ankle with his studs in the box.
The referee's decision to point to the spot was eventually ratified by VAR with Lionel Messi nonchalantly chipping in from 12 yards to put the hosts on their way to a 5-1 victory.
However, the Lyon president was left furious by the decision and believes it set the tone for their downfall at the Nou Camp despite UEFA assuring him that VAR was working at the time of the review.
'Today, you cannot say it is a real success. When that happens in an unbalanced match, one could imagine that it does not have a bearing on the result,' Aulas said.
'But here, I feel that it really penalised our team and that we had a few weaknesses after that.
'Barcelona were better, but there was not as much of a difference between the two teams as the result indicates.'
Philippe Coutinho doubled Barcelona's lead not long after Messi's opener from the penalty spot.
Lyon grabbed one back through Lucas Tousart but another strike from Messi, and goals from Gerard Pique and Ousmane Dembele ensured safe passage into the quarter-finals for Barcelona.
Meanwhile, VAR continues to face questions over its reliability and competence after making a controversial introduction to the Champions League last month.
A number of dubious decisions have already been given via VAR and the pitch-side video monitor was not functioning properly during Manchester City's first-leg clash with Schalke in Germany - resulting in the referee being ordered to give a penalty without seeing a replay of the incident.
