Manchester City fullback Bacary Sagna says France teammate Antoine Griezmann is as good as any player in the world.

The Atletico Madrid ace has been outstanding for the hosts at this summer's Euros.

"Ronaldo, we know him. He's one of the best players in the world -- if not the best -- and he has worked very hard to get there," Sagna told a news conference on Saturday.

"Antoine, to me, is right up there too, in the same league as Ronaldo and Lionel Messi."

On Griezmann's success, Sagna added: "It's a kind of revenge for him after the French academies wouldn't take him.

"He made it the hard way and he deserves to be where he is."
