Former Arsenal midfielder Aaron Ramsey has spoken of working with Juventus teammate Cristiano Ronaldo.

Ramsey joined Juve from Arsenal last summer.

"He's an exceptional athlete," Ramsey said in a social media chat.

"He's first in the gym, he goes through his routine and then he goes out onto the pitches.

"He's a winner. He wants to win every small-sided game, whatever it is.

"Then he will be out there practicing his free-kicks, shooting, whatever.

"You don't need me to tell you how good or how driven he is. He is just unbelievable and he is one of the greatest in the game."
