Former referee Urs Meier has urged UEFA to impose a strict punishment on Chelsea coach Jose Mourinho if he is found guilty of bringing the game into disrepute.

“A penalty has to hurt,” Meier, who retired at the end of last year, told Stern magazine in an interview published on Tuesday.

“If Mourinho got a suspension and was not allowed to sit on the bench in the quarter-final against Bayern, that would hurt.”

Mourinho is on a disrepute charge from UEFA for suggesting that referee Anders Frisk influenced the result of Chelsea’s 2-1 first-leg defeat by Barcelona.

Chelsea play Bayern Munich in the first leg of the quarter-final on April 6, with the return in Germany on April 12.

“For about the last year players, trainers and clubs have been testing the boundaries,” said Switzerland’s Meier.

“The boundaries have been crossed but nothing happens.”

Frisk quit refereeing after receiving death threats from Chelsea supporters and the Swede has resisted all attempts to persuade him to return.

Meier himself was the recipient of death threats after he disallowed a Sol Campbell goal for England against Portugal at Euro 2004.
