UEFA are treating Thierry Henry's allegations of racist abuse during Arsenal's Champions League clash with PSV Eindhoven "very seriously" and will begin an investigation.
Henry revealed he was the victim of racist abuse and had missiles thrown at him while taking corners during the Gunners's 4-0 win in the Philips Stadion.
PSV were handed a one-match ban from playing at home in March 2001 following crowd trouble during their UEFA Cup quarter-final match against Kaiserslautern. Now they may be in trouble again.
UEFA spokesman Mike Lee said: "Once we've completed the investigation, if the evidence is there, and we believe it is then this will be referred to our disciplinary body. It is Eindhoven's second offence so we have to look at it very seriously".
Referee Lubos Michel was seen to pick up various objects thrown onto the pitch during the second-half and he is therefore likely to include the incidents in his official match report.
At worst, UEFA could bar PSV from hosting further Champions League games at their home ground, although a fine is probably a more likely punishment if they are found guilty of any misconduct charge.
