Jose Mourinho is Manchester United's "biggest ever signing", according to the man who first brought him to England with Chelsea in 2004.

Peter Kenyon - the former United and Chelsea chief executive - insists the Old Trafford club have got the best manager in football and expects him to be a success.

Speaking to Sky Sports News HQ, Kenyon said: "Quite simply, they're getting the best manager coaching in football today. His track record speaks for itself.

"When I appointed him, I was looking to bring a winning mentality to what was already a good team. Jose brought that immediately, which led to the first title in 50 years, in that first season - that's the ability he has.

"He's got a great ability to make good players better, so I think the current players at Manchester United will be better under Jose Mourinho, for sure.

"It's a really exciting time. He is a coach who brings new techniques, new developments. He's very forward thinking. He'll make the necessary changes that are required and have an immediate impact."

Kenyon left United to join Chelsea in 2003 and he insists Old Trafford is a different place from when he was there under Sir Alex Ferguson.

Kenyon believes Mourinho will do things his own way, and attempt to move the club on from Ferguson's reign.

"With David Gill and Alex going it's a different organisation. Jose's not there for a season, he's there to rebuild Manchester United and I think he's the perfect person to do that," Kenyon said.

"Jose will do it his own way. Jose knows how to win, he knows how to build the best teams, he knows how to create the atmosphere for players to develop to the very top level and win trophies, and that's what he'll be doing.

"I don't think he sets out any day to disrupt but he doesn't take prisoners. That's proved successful and that's what Manchester United are getting."
