Instead, Dutch coach Louis Van Gaal said: 'I never have fear and my players don't have any fear either. We value Rooney's quality. He is a super footballer.
'When he was younger, I often wondered whether he had the vision in his game. He has developed that now and is very hard to mark out of the game. But we can manage because we also have quality. Ferguson and his players should be scared of that.'

Ferguson added: 'The return of Vidic and Ferdinand to keep our backfour solid is significant. Along with Edwin van der Sar there was atime when all those players were injured. It wasn't easy and we werevery fragile.
'But you can see the solidity now. You can see the experience ofthese players and it is making a massive difference to the performancesof the team. It is a true saying: strong at the back, strong as ateam.'
Ferguson also took the chance to defend Nemanja Vidic against asuggestion by Bolton manager Owen Coyle that the Serb centre halfdeliberately elbowed Johan Elmander during United's 4-0 win at theReebok.
The United manager said: 'What's the story about those in glasshouses? Vidic came in at half-time with a lump on his head, a swollenjaw and a black eye.
'It was clear he had his eye on the ball, there was no intentwhatsoever. That was the best performance from a centre back for years.'
