Olympics sprint champ Usain Bolt says he told Manchester United boss Sir Alex Ferguson to make sure of victory against Wigan Athletic last week.

Bolt told BBC Sport: "I made a call to Alex telling him that losing is not an option because I've been winning and he just talked to the guys to let them know to get it done.

"First of all I would like to say thank you guys for winning. I'm really happy right now, it's going to be a wonderful night for me. Wayne Rooney's a great guy, he's going to lead US to the championship this year for sure. He's the leader his year and I think he's going to do a wonderful job definitely"
