Matt Roberts presents live coverage of the Czech MotoGP from Brno. Reigning champion Valentino Rossi has showed he has no intention of giving up his crown in 2009, and the Italian rider will look for a fourth win at the Czech circuit. Rossi racked up his 100th Grand Prix victory earlier in the season, and few events were more fortunate for him than the one at Brno in 2008, when Casey Stoner skidded into the gravel while comfortably ahead to give Rossi victory.
