Marc Marquez believes the lack of pressure on his shoulders since winning the MotoGP world title for a third time has impacted his results in the last two races.
Marquez clinched the title with victory at the Japanese Grand Prix at Motegi last month as nearest rivals Jorge Lorenzo and Valentino Rossi both crashed out of contention.
The Repsol Honda star failed to finish in the subsequent race in Australia before coming home in 11th in Malaysia.
Marquez will now aim to finish another title-winning campaign on a high in Valencia this weekend.
He said: "These last two races were not the best way to celebrate the title but it looks like I need some pressure to be always concentrated and to finish all the races, like when I was fighting for the title.
"But here, it is a circuit that I like and I will try to do my best. The last two races have been not so good on Sunday but the performance was very good.
"Here in Valencia is it always great and nobody this year has [any extra pressure] so more or less everybody will push at 100 per cent."
Looking ahead to next year, Marquez added: "On Tuesday and Wednesday the 2017 season starts already so we must be very concentrated to try to improve our bike because I think we have many things that we can improve - we just need to find a way.
"Already I don't speak a lot about the test because I want to concentrate on this weekend's race and then on Monday we will speak about the test, but yes it is important to start in a good way for 2017."
