Michel Platini: Mario Balotelli, walk off over racism and you'll be booked at Euro 2012

Michel Platini has warned Mario Balotelli that if he were to walk off the pitch for being racially abused – as he suggested he would last week – during a match at Euro 2012 then he would be booked. The Uefa president insists players should instead talk to the referee, who can decide whether to stop the game.

In his opening news conference here yesterday, Platini said referees were fully empowered to halt matches temporarily, or abandon them totally, if racist abuse was directed at players from the crowd.

Balotelli said last week that he would leave the field of play if he was targeted, but Platini warned the Italy forward, and every other player, to do nothing rash. "We will certainly support the referee if he decided to stop the game. But it's not a player, Mr Balotelli, who's in charge of refereeing. It's the referee who takes these decisions. So, the referee has been given advice and he can stop the game if there are problems. But it's not me, not the Uefa president, who is in charge of the game for 90 minutes. It's the referee. We will support the referee, of course – always."

Pierluigi Collina, the former World Cup final referee who is now Uefa's chief refereeing officer, added that the European governing body's officials had visited all 16 teams and explained the procedure to stop the game.

Collina said that if a player complained to the referee about racism, the referee would take the necessary action. "The referees have a protocol so they know what they have to do. The match director knows what has to be done. The players know the protocol. We have visited all the camps before the start of the competition, so everything is clear and everyone is ready."

Piara Power, executive director of Football Against Racism in Europe, who was also at the briefing, said afterwards: "There is no question we are more worried about racism at this tournament than at any other, and it is good to know that Mr Platini understands what is going on.

"We have 31 independent international monitors and it is their job, not just to look out for the more obvious racism, but also the nuanced issues, that is certainly not the job of the referee. Their job is to pick out right-wing banners and insignia, and discriminatory chants and to provide ongoing liaison with the match delegates.

"We are expecting that Uefa's disciplinary commission will sanction any fans displaying far-right banners as there have been at past Euros. The Uefa system is three strikes and you are out.

"A fine, then another fine, then forcing teams to play behind closed doors. If the system is in full effect we could have a team kicked out of the competition for far-right banners."
