* Vieira:
"Roy Keane knows Manchester United so well. He has been one of their greatest players and one of the greatest captains the game has seen. He was there for so long as a player and has learned a lot from Alex Ferguson. I think he may be the future United manager.
"It wouldn't surprise me at all - and he would be a success. I was quite surprised he went into management as soon as he did. I thought he might want to take a bit more time out but, when you have football in your blood, it is always there. You have that passion - you always have it. I have massive respect for Roy Keane. He was tough, he was hard but I loved our rivalry. I have a big respect for him as a player. He won everything with United, he was a fantastic footballer."
* The Sunday Mirror report that United will sign Jermain Defoe from Tottenham in the summer.
