He told manutd.com: "Yeah, we have got the sort of players who can change roles. Wayne Rooney sometimes plays on the left, Ronaldo on the right, Louis Saha up front, myself just off the front. But it doesn't always stay like that. Wayne can come in, I can go out wide, Ronaldo is capable of swapping. So we've got that fluidity really, and we've got personnel who can interchange. Often last year that really worked for us.
"We're talking about class players here with real imagination, so the creativity that the players have got, they use it. But we also work at it on the training pitch. Sometimes you have to hold your position, others you have to be more structured, but sometimes you've got the licence to go wherever."
