Gavin And Stacey's Smithy is set to show tennis ace Andy Murray how to make it to Grand Slam glory.

Actor James Corden teams up with the British sports star as part of his spoof sketch for this year's Sport Relief - and gives him tips on how to up his game.

The meeting is part of Smithy's one-man mission to motivate sporting greats for the TV charity fundraising efforts, to be screened on March 19.

He also meets the Manchester United squad, diver Tom Daley and Formula One star Jenson Button.

The sketch follows last year's pep talk to the England football team for Comic Relief's Red Nose Day.
