Rossi's teammate Lorenzo scored a lights-to-flag victory to be crowned MotoGP champion for the third time on Sunday,

Although Lorenzo was under pressure from Repsol Honda rider Marquez for much of the race, Marquez didn’t make any clear attempts to overtake him.

Instead, Marquez blamed his teammate Dani Pedrosa for attacking his second place with a lap and a half remaining, and he repassed Pedrosa almost immediately.

Following the race, which Rossi started from the back of the grid after his controversial collision with Marquez in Malaysia, the seven-time champion launched his verbal attack to the media.

"Today everyone has seen their plan, this makes me sad and it's a very bad thing for our sport,” said Rossi. “I do not understand why a Honda rider allows Yamaha to win [the race]. I hope this behaviour in time turns against him.

“Lorenzo is a very good rider, it would be nice to battle on equal terms, but I think even he wouldn't be very happy to have won like this.

“I am sad that Marquez acted as bodyguard for Lorenzo. I had already said on Thursday, I was convinced that they would go to the end [with their plan], I was sure they would have conspired against me, as happened in football [Rossi has referred to the infamous so-called ‘Nordic fix’ match when Sweden and Denmark allegedly conspired to knock Italy out of Euro 2004].

“I don't know if Marquez protected Lorenzo because they are both Spanish, but it's sad he chose to be his bodyguard. Lorenzo has never done what Marquez did. But for his behaviour after Malaysia [when he attempted to join the court proceedings], he deserves to be treated like Marquez.

“I'm sad, a great opportunity has vanished and I did not deserve this.”
