'Wayne is definitely the best striker in the world,' said Vidic. 'And after sharing the same dressing-room, it would be fun to play against him.
'I mentioned to him that if we got through we have a chance to meet England. I said it would be an interesting game. He said "Serbia? Who plays for them?". He was joking.
'One of us would have to lose and he's a great player, who would be hardto keep quiet. But that's the challenge. That's why you play football.

'He knows we're doing well and he knows we're not an easy team, even though England are a big one.'
Vidic conceded Rooney would be a difficult proposition, saying no matter how many lumps he could kick out of him, the forward would probably still be standing!
He added: 'I don't kick so many players. I would kick him more in training. Wayne is strong and he has pace. For a defender, players like that are always difficult.'
