Patrick Vieira said he was shocked by racial abuse directed at black players during Paris St Germain’s match against Lens on Sunday.

Fans in the at the Parc de Princes unfurled a banner that read “Come on whites”! and racially abused black players on either side.

“I have not played at the Parc des Princes for a long time,” Vieira said on Tuesday.

“And I’ll think twice about it before I’m going to go there again.

“In England such abuses are not tolerated any more. There are video cameras which help track racist supporters. And once they are spotted they are banned.

“Similar sanctions could be taken in France. I was really shocked by what I saw at the Parc des Princes. It’s up to the club to sort out this problem.

“The French soccer federation must give them a hand and FIFA must give the federation a hand too.”

PSG sported an all-white strip on Sunday, while the visitors played in black as part of an anti-racism campaign that is being spearheaded by Vieira’s Arsenal and France team mate Thierry Henry.

“This is urgent to do something as things are getting worse,” said Vieira. “People must be reminded that there are things that can’t be said.”
