He may not have got the world in motion, but Smithy is keeping Manchester United on their toes. Actor James Corden - famed for bursting into the rap from New Order's World In Motion in TV hit Gavin And Stacey - was putting players through their paces by leading an aerobics class. The tubby star filmed the sketch with stars such as Wayne Rooney and Rio Ferdinand - to be aired on Friday March 19 - for this year's Sport Relief spectacular on BBC1. Smithy puts aside his loyalty to West Ham to take charge of the Man U squad, giving players such as Michael Carrick and Wes Brown a training session they will never forget. Last year, James gave a hilarious pep talk to the England team. A sneak preview of the routine will be screened during Match of the Day Live's coverage of the Carling Cup Final on Sunday. Other sporting figures are expected to be whipped into shape by the Billericay boy in the full sketch. Other Sport Relief highlights include special editions of Strictly Come Dancing, MasterChef and A Question of Sport Relief. CLICK below to watch Smithy's aerobics class with Man Utd
