Juventus this morning announced they would appeal against the punishment meted out to the club following the racist chants that marred their Serie A match against Inter Milan on Saturday.

Italy's disciplinary chiefs decided Juve must play their next home league game behind closed doors after sections of the crowd directed abuse at Inter's Ghana-born striker Marco Balotelli during Saturday's 1-1 draw.

But Juve legend Platini believes more immediate action needs to be taken in order to combat racism in football.

"Courage is needed," said the Frenchman, who is in Rome to hand over the Champions League trophy ahead of the final on May 27.

"From now on, the line of UEFA in a case of racist chants will be to stop the game for 10 minutes and, if it continues despite announcements, to suspend the game completely."

Juve coach Claudio Ranieri admitted the supporters in question on Saturday were in the wrong but labelled the ban "unjust".

"Our lawyers will deal with this," he said of the appeal.

"The stadium ban is unjust. This is not a recurrent incident as it was just one game.

"In any case, the behaviour (of the fans) was not correct.

"I am close to the lad (Balotelli) and I am very saddened for what has happened but I reiterate that it is right for us to appeal."

Bianconeri president Giovanni Cobolli Gigli earlier voiced his anger over the abuse aimed at Balotelli.

"In the name of Juventus and the majority of its fans, I express condemnation for the racist chanting directed at Inter player Mario Balotelli," he said.

"There are no excuses and no justification for that behaviour. Episodes like this are unacceptable."
