Barcelona defender Gerard Pique believes Wayne Rooney will fire Manchester United to the Premiership title next season.
Former United centre-half Pique believes England's South Africa pain will prove to be the Red Devils' gain.
Pique told the Daily Star Sunday: ''England's World Cup and especially the nature of his own personal performances would have really hurt Wayne.
"But I strongly believe England's disaster will be Manchester United's gain. I have never seen a player in football who gets more upset and frustrated by defeat than Wayne.
''People can talk about how, with the player's wages, they don't care about defeat or about the fans.
''But anybody who thinks that, needs to see Wayne in the dressing room after a defeat. You don't even want to talk to him. He looks like he is going to explode. Most players cool off over the weekend but he will come into training on the Monday with even more intensity and desire. And I think that is what will happen when he gets back in the groove with United.
''Even on his holiday with his family I know the World Cup will be hurting him. But he is the sort of player who will turn that hurt into a title-winning season for Manchester United.''
