if there's a chance that Rooney could make his injury worse and risk missing games for Utd next season then Sir Alex will do everything he can to stop Wayne from joining the England squad for the World Cup...

it's like Beckham in the last World Cup, he was rushed back from injury and then hardly performed in the competition itself because of lack of match fitness...

if Wayne isn't ready when the times comes then he should stay at home and rest for next season...
