MotoGP world champion Marc Marquez believes that his biggest threat next season will come from Yamaha rider Jorge Lorenzo.

The 27-year-old hampered his chances of winning the crown in the early stages of the season following a first-lap crash in the opening round, but managed to eventually finish third in the rankings.

While Marquez believes that his Reposl Honda teammate Dani Pedrosa and Valentino Rossi will be in contention for the 2015 title, the Spaniard is more worried about Lorenzo.

Marquez told MCN Sport: "You never know with Valentino. I didn't expect his level. I expected more like last year (2013), but he will be there because his motivation is there and Dani is always constant.

"Maybe he won't be better or worse than you but he will always be there and you need to pay attention with him. But I expect Jorge will be the strongest rival."

Marquez will be aiming for a third consecutive premier class title.
