Nicky Hayden rode alongside eight different team-mates during his 13 season😼s in MotoGP, which came to an end at last month's Valencia 💖season finale.

So which of t✨hem impressed the 2006 world champion the most?

"I could write a book on my team-mates because there have been a lot of di🦩fferent personalities over the years and I've learned a lot from each one," Hayden said.

"For sure, Casey for outright speed was incredi🉐ble. His ability to find the limit on a wet or dirty track is something I'd never seen before. And you know Dani, the way that he gets the bike off the corners is incredible.

"But I think the person who impressed me the most has to be Valentino. Because I was his team-mate twice and the Ducati days when it was🍨 really low - for him to come back from that is extremely impressive.

"And at 36, to have as much success and money - he has everything. But to still have that same passion and fire﷽ is something that I found motivating. I think that's been more impressive than anything on track."

Hayden is moving to WSBK in 2016, riding for the Ten Kate Honda𒊎 team.
