Paris Saint-Germain’s anger with their stunning Champions League exit shows no signs of abating after it emerged that the French club have sent a five-page dossier to Uefa to complain about the performance if the referee during their 6-1 defeat by Barcelona last Wednesday.

PSG looked all but guaranteed a place in the Champions League quarter-finals following their 4-0 victory in Paris last month, but the tie was turned on its head as Barcelona became the first team to overcome a four-goal deficit during the knockout stage of the European Cup.

The game did not go without its controversy though, with the Parisian side deeply unhappy with referee Deniz Aytekin, and they have since employed a team of experts that includes former international referees to compile a list of the errors that the German referee allegedly made during the 6-1 defeat, according to The Telegraph.

Aytekin awarded Barcelona two penalties during the Nou Camp encounter, and PSG are unhappy with the way he handled pressure from the Catalan side’s players when making key decisions during the match.

They have also raised decisions that went in Barcelona’s favour that were deemed questionable, with video evidence and photographs included to back-up their arguments. One such incident was the decision to book the Barcelona striker, Luis Suarez, for diving, only to award him a penalty after appearing to go down to the ground just as easily in the 90th minute.

Another case surrounds the failure to award PSG a spotkick when Javier Mascherano appeared to foul Angel Di Maria in the area, with the Barcelona defender admitting afterwards that he believed it was a penalty. “It is clear that I did foul Di Maria but I think that is not the reason why we eliminated PSG,” Mascherano said after the match.
