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

So which of t𒆙h🌄em impressed the 2006 world champion the most?

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

"For sure, Casey for outright speed was incredible. His ability to find the limit on a wet or d꧋irty 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 Du🔯cati days when it was really low - for hiౠm 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 imღpressive than anything on track."

Hayden is moving to WSBK in 2016, riding for the Ten Kate Honda tea📖m.
