Matt Roberts presents live coverage from Sepang of the Malaysian MotoGP, the penultimate race of the season. Valentino Rossi may have already claimed the overall victory, but his rivals will be sure to try and stop him from winning another race. One driver who will be particularly determined is Casey Stoner, who triumphed at Sepang last year and went on to become World Champion - will he be able to lay down a marker for next year's contest? With commentary from Charlie Cox and Steve Parrish.
