Matt Roberts presents live coverage from the Malaysian MotoGP, the penultimate race of the 2008 season. Valentino Rossi has already clinched the title but his rivals will be keen to prevent him landing yet another victory in what has been a terrific season for the Italian. Casey Stoner won at Sepang last year, becoming the first rider to win all three classes in the Malaysian event, as he continued his march towards his first MotoGP crown. A poor recent run for the Australian cost him his hopes of retaining that title but victory this weekend would be a good way of laying down a marker for next season.
