PSV were handed a one-match ban from playing at home in 2001 following crowd trouble during their Uefa Cup quarter-final match against Kaiserslautern.

Now they look to be in trouble again with Uefa spokesman Mike Lee promising action following last night‘s incidents.

“We‘re going to investigate it,” Lee told BBC Radio 5 Live. “I spoke to the venue director last night and he said there was evidence of racist abuse which we obviously totally condemn.

“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.

“Clubs tend to appeal to so we have to be considered in the way we go about it and it‘s not something that Uefa can solve on it‘s own.

“Everyone in football has a responsibility here. The national football associations, the clubs, the fans, the police.

“A combination of education and disciplined reaction is what we do to tackle it but, sadly, it keeps arising and it‘s something football should be ashamed of.”

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.

Uefa will no doubt wait to receive that report, as well as the views of their official delegate at the game, Italian Pierino Lardi, before asking PSV and Arsenal for their views.

At worst, they 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.

Henry said last night: “They were throwing coins, lighters and other stuff. I don’t know whether you heard what they were saying or saw what they were doing.

“Obviously I have two ears but you didn’t see me shout back. The referee was doing his business and I was just waiting to take the corner-kicks.”

Gunners boss Arsene Wenger said: “That sort of behaviour is terrible and it should be banned. I think that Uefa will react.

“We did not feel under threat but there are always some crazy people in every crowd. It’s up to Uefa to react and we have full confidence in them to do that.”
