He may not have got the world in motion, but TV comic James Corden is keeping Manchester United on their toes.
In character as his Gavin and Stacey alter ego Smithy, the tubby TV funnyman was putting players through their paces by leading an aerobics class.
But rather than improve their fitness, he left stars such as Wayne Rooney and England captain Rio Ferdinand in fits of laughter.

The comedian has been trying to get Beckham on board again for this year's Sports Relief sketch.
The ideais believed to be based on Smithy giving the LA Galaxy/AC Milan star amassage.
