Nine-time world champion Valentino Rossi insists the performance of Marc Marquez in the Valencia MotoGP title decider confirms his claims that the outgoing world champion was helping countryman Jorge Lorenzo win the 2015 title.

While Rossi, 36, was able to slice his way through the field for fourth position at the finale from the back row of the grid, Marquez trailed Lorenzo for the entire 30-lap duration without mounting any major attacks.

“We build this season from the first race and at the end it was anyway a great season,” Rossi said. “I was always competitive and never make any mistakes. I think that after Motegi I have the potential to win the championship but unfortunately from the race in Phillip Island something changed and in these last three races we saw something that we never saw before in our sport.

“I think that the situation was already bad, but today was embarrassing for everybody because it was unbelievable, the behaviour of Marquez is something very bad for everything, especially for the sport.

“It is something that nobody expects, because a Honda rider that made a Yamaha rider win and give the maximum just to push out his teammate is something that nobody expect and I think it is very, very bad news. Anyway, it is like this, we have to accept.

“I am happy because now everybody see what I said in Australia and I don’t understand the behaviour of Marquez but sincerely for me it is very difficult to say something to him because I hope that he will understand what he did in these last three races in the future of his career.

“For sure the Hondas were faster. We know that in the second part of the race Honda have a better potential but Marquez just protect Lorenzo like he did in Phillip Island and also Sepang. At the end I think that also Lorenzo have to not be very happy, as it is not a championship that was won on track. But anyway is memories.”

Rossi was forced to start his bid for a 10th title at the final race from the rear of the grid following his controversial clash with Marquez a fortnight ago at the Malaysian grand prix.
