London, Apr. 6 : Olympic sprinter Usain Bolt has labelled Manchester United star Cristiano Ronaldo a "wuss".

The super-fast Jamaican athlete is visiting the Premier League champions next month to pass on some running tips.

But Bolt, a Manchester United fan, is also planning to have a word with Portuguese star Ronaldo about his play-acting and "falling over," reports The Sun.

Bolt, 22, who has a long-standing invitation from boss Sir Alex Ferguson to visit Old Trafford, said: "I'm going to tell Ronaldo to stop being such a wuss.

"I'd like to see more of Wayne Rooney's fight in Ronaldo. He has to be aggressive like Rooney, even if it gets him into trouble at first.

Double world record holder Bolt also said of Ronaldo, who scored twice against Aston Villa yesterday: "His problem is that when he runs he leans forward and loses his balance. He needs to sprint more upright."

Bolt, who is coming to Manchester for the Great City Games in mid-May, will meet United players at their training HQ. He will watch their home game against Arsenal on May 16. (ANI)
