Paris St Germain have expressed their "fullest support" to fans who travelled to the Champions League match against Chelsea Women, where weapons, fireworks and drugs were found on board a supporters' coach.
Before the first leg of the quarter-final tie at Kingsmeadow, a coach carrying about 50 PSG fans, who had travelled to London from France overnight, was turned away from the ground.
The Metropolitan Police said "knives and knuckledusters" were recovered while one man was arrested for possession of class A drugs.
There were also reports of vandalism at the stadium during Thursday morning, as well as disorder later on at Waterloo and Wimbledon stations.
Despite the widely-reported incidents, PSG issued a club statement on Friday morning criticising the handling of the situation and claiming no damage had been caused at the stadium by their fans.
"We repeat that the local authorities have not provided any evidence of wrongdoing, at least no fact available justifies such a ban to attend the match," the PSG club statement read.
"All of our supporters have been searched, and if any of these searches or facts had been under criminal law, we can imagine that the concerned supporter(s) would not have been able to leave British territory without being disturbed.
"Surprisingly, we note that Chelsea, on the morning of the match, did not want the presence of our supporters, arguing of alleged damage to the stadium which is, according to local testimonies, prior to the arrival of our fans in London.
"We express our fullest support to fans of Paris St Germain who, in the middle of the week, had arranged their schedule to come support our women's team and we count on their fervour during the return match next Wednesday in Paris."
