The Roma midfielder is facing a suspension after being caught on camera striking Mauro Icardi during Saturday's 0-0 draw with Inter
The Roma midfielder is likely to be suspended after being caught on camera seemingly striking Inter forward Mauro Icardi during Saturday night's Serie A clash between their respective sides at the Stadio Olimpico.
Prandelli therefore decided against including De Rossi in his squad for Wednesday's international friendly against Spain, explaining that the goal is to hammer home to players that they will not be called upon for this summer's World Cup in Brazil unless he knows that he can rely on them to keep their heads.
"It's our rule and I'm the judge," he declared at the launch of Italy's new PUMA strip in Milan on Monday. "I don't have to wait for television evidence. If I believe that the players have behaved badly, they aren't called.
"I do it for them. For the World Cup, I want players that will be ready in every way. I don't want to play with 10 players. I don't want reckless acts [on the pitch]."
Antonio Cassano has had his own disciplinary problems in the past but the forward is currently enjoying a productive campaign with Parma.
The 31-year-old did not make the squad for the midweek visit to the Vicente Calderon but Prandelli insists that the door remains open for all.
"I'm not excluding anyone at this stage," he stated. "There are still over two months of the season to go. After that, then we'll see."
Prandelli added that Alessandro Diamanti's surprise decision to leave Serie A side Bologna for Chinese Super League outfit Guangzhou Evergrande could affect the attacker's hopes of boarding the plane for Brazil.
"It was a big decision for him, in terms of lifestyle and his family, and also because I certainly cannot watch him in action every week," he confessed.
"It puts a question mark over his participation in the World Cup."
