Fulham midfielder Damien Duff believes Jose Mourinho will struggle to repeat his success at Chelsea second time around.

The former Stamford Bridge winger won two titles under him in Mourinho's first spell in London.

Fulham star Duff, who spent three years as a Chelsea player, said: "Usually I would say that it would be a no-brainer for Mourinho to win the league title.

"But this will be an exciting year in the Premier League, with Manchester City getting a new manager and Manchester United being so strong.

"Jose is an amazing manager - as good as there has ever been in the history of the game.

"But it will be tough for him - even if he has a history of coming up trumps."
