AC Milan midfielder David Beckham doesn't expect Manchester United striker Wayne Rooney to suffer burnout ahead of the World Cup.

Injury is a constant hazard for any player but Beckham scoffs at the threat of burn out.

"Burn out will not be a problem," he said.

"Of course he can sustain that level until the middle of July. He should be able to. He is only 24.

"He looks after himself and works hard. The way he plays is the way he trains. That is why he is so good and why Wayne is ready for any game.

"It doesn't matter how many games he has played or how many he will be involved in to the end of the season, he will be ready for anything."
