Buriram, (Thailand) Oct 2 (IANS): Marc Marquez needs just two points over Italian Andrea Dovizioso to proclaim himself the MotoGP world champion for the sixth time in his career.

The Thai Grand Prix taking place at the Chang International Circuit in Buriram should be the decisive race between the two riders. New on the MotoGP World Championship calendar since last year, the Thai circuit of Buriram has only one winner and it is Marquez, though he had to wait until the last lap to emerge victorious by 0.115 seconds over Dovizioso.

Sticking to the results achieved in the current season by Repsol Honda's team leader, except for the Spaniard's fall at the Americas GP in Austin that left him without scoring, would make Marquez worthy of the title, reports Efe news.

If Dovizioso wins or is placed second or third, ahead of Marquez in Thailand, Marquez would not be the world champion as he has to outscore the Italian by two points.

Any other result Marquez would get in addition to the two points would make him the champion. In addition to the world title, there are other points of interest ahead of the Thai race.

Alex Rins was one of the team's chances to win the Aragon GP, but his performance was not that good having finished ninth.

In Buriram, a circuit that is favourable and in which Rins had finished sixth last year just three seconds behind the winner, could be his chance to win.

Italian Danilo Petrucci, the second Ducati driver, seeks to snatch the third spot in the standings from Rins, a position that Maverick Viñales and Valentino Rossi could also fight for.

However, Frenchman Fabio Quartararo has two very different clear objectives.

The first is to continue with the progress that has brought him to the verge of victory in a couple of races, in which he had finished second.
