The MotoGP World Chaion Valentino Rossi has turned down an offer from former Formula One driver Jean Alesi to race with the Frenchman in the Le Mans 24 hour next June.
Rossi says he wants to solely concentrate on winning another world title.
Rossi, who has competed in several events on four wheels as he ponders one day switching sports, was due to race in the Mexico Rally in March but Brivio says his participation was now in doubt as it comes too close to the start of the MotoGP season.
