Manchester United boss Sir Alex Ferguson admits he's a fan of both Jose Mourinho and Pep Guardiola.

Both Real Madrid coach Mourinho and former Barcelona boss Guardiola are in line to succeed Ferguson at United.

He said in a lecture at Harvard Business School: "Jose is very intelligent, he has charisma, his players play for him, and he is a good looking guy.

"I think I have most of those things, too, apart from his good looks.

"He's got a confidence about himself, saying 'We'll win this' and 'I'm the Special One'.

"I could never come out and say we're going to win this game. It's maybe a wee bit of my Scottishness?

"Guardiola is an impressive guy. He's brought about change in Barcelona, urging the team to always work hard to get the ball back within seconds after losing it.

"They are gifted but work hard. It was a fantastic achievement. He elevated the status of his players."
