Cal Crutchlow is in no doubt t🅺hat reigning MotoGP World champion Casey Stoner is the 'fa🌊stest man on the planet'.

The injured Monster Yamaha Tech 3 star also reckons Aussie Stoner has not received t💝he credit he's deserved in recent seasons and admitted he was 'disappointed' by news of Stoner's retirement from MotoGP at the end of 2012.

"It was more disappointing for everyone else than it was for him," Cruওtchlow said on Stoner's shock decision.

"People don't really give him credit for how fast he is - ▨he is by far the fastest guy on the plane💞t.

"Maybe over the years he just hasn't put the championship together, whether that's because of machinery or himself sometimes, but he's by far the fastest guy and when he did get th🥀e machinery, he went and won last year.

"And when he won the title before, he maybe didn't have the best machinery, but he was the best guy," added the Briton, who was speaking during a live webchat wit✤h on Bennetts Bike Insurance Facebook page.

"In🀅 all honesty he's leaving the sport for reasons that are correct in some ways and him lea🌠ving the sport is a wake-up call for some people.

"But if his pa꧑ssion for the sport isn't there any more then I think he's right to retire and he's def💙initely done a great job and left a legacy as well.

"I think he'll stop and that will be it. He's d💯on൲e everything in motorcycle racing," Crutchlow added.

"MotoGP is the pinnacle and 🔥if you can win in MotoGP then that's the♏ top.

"Hopefully for his sake he can win this year for the third time an༒d leave on a high."
