Marc Marquez sealed his sixth MotoGP world title in Thailand on Sunday after storming to victory in a heart-pounding final corner duel with Fabio Quartararo at the Chang International Circuit, but said it had not been an "easy" year as the frontrunner.

The win in Buriram gives him an insurmountable lead over closest rival Andrea Dovizioso with four races left in the season.
Spain's Marquez finished in 39min 36.223sec just ahead of 20-year-old rookie Frenchman Quartararo with another Spaniard Maverick Vinales third.
Marquez jumped up and down with joy after the victory and was handed a large eight-ball to signify the eight overall championships across all classes he has won.
He was hoisted atop the hands of supporters in celebration.

Quartararo held the lead through 25 of the 26 laps but Marquez made his move on the final circuit, flying past the leader as the crowd screamed in delight.
Marquez told reporters that it was now "time to enjoy it" after a high-pressure season with many competitors...
