Marseille are set to file a complaint to UEFA regarding the treatment of their fans and alleged racism during their Champions League match with Atletico Madrid on Wednesday.
Marseille president Pape Diouf admits he was left with a bitter taste following the incidents at Atletico's Vicente Calderon stadium, and believes European football's governing body needs to act.
The ugly scenes involving the travelling Marseille fans took place in the build-up to the match when supporters clashed with baton-wielding riot police and stewards for around 10 minutes in the away section of the ground.
Those crowd disturbances were not the only incidents that incurred Diouf's ire, with the Marseille chief claiming his club were again the victims of racist insults and questioning UEFA's approach to dealing with the problem.
“You have to also know that we have already been victims of these types of racist insults, it was at St Petersburg last season,” said Diouf on his club's website.
“That wasn't worth more than just a 30,000 euro fine to that club. I understand, therefore, that this type of thing can happen again.
“What's upsetting is that the UEFA dignitaries want to impose themselves here or there to eradicate all forms of violence and racism from the stadiums, and yet, when you see how they punish these kind of acts when they happen, we could pose ourselves questions on the sincerity of their approach.”
When asked if his club would be taking up the matter with UEFA, Diouf added: “That's certain because we can't just sit back and do nothing.”
