Patrive Evra thinks Manchester United boss Sir Alex Ferguson will stay in charge of the team until 'his last breath'.

Evra was convinced of Ferguson's vitality after witnessing his manager dancing in the dressing room 'like a child' after overcoming Manchester City in the Carling Cup semi-finals.

"Sir Alex is a child. We saw it against Manchester City. He's so passionate," he said in The Sun.

"He was jumping up and down like a child after that game.

"You could be forgiven for thinking he'd never won a game before!

"At 70, he doesn't see himself taking it easy at home reading a book or watching TV. Personally I think that would bore him.

"I don't think he will call an end to his career. As long as he's strong he will carry on.

"He will stay until his last breath."

Man United will meet Aston Villa in the Carling Cup final on 21st February.
