Felipe Massa suspected Nelson Piquet crashed deliberately during the Singapore Grand Prix last year and confronted Flavio Briatore about the incident in person, it has been claimed.
The report, made by Brazilian television commentator Reginaldo Leme according to motorsport.com, suggests that the source of the accusations against Renault may not be its sacked driver Nelson Piquet, as had been previously suggested.
"He crashed in a very strange way," Leme is quoted as saying. "It struck me when I was talking recently with Felipe Massa. Felipe had gone to Briatore and said, 'This crash was not right, it happened because you wanted it to'."
Massa lost his chance of winning the race when he left his pitstop with the refuelling hose still attached. he eventually finished 13th.
