It's been suggested Griezmann is the antithesis of Benzema after the latter's omission from France's Euros squad.

"We must learn to forget. I'm also lucky.
"I was 18-19 years old. I was a kid who had just arrived in the pro world and thought he could do what he wanted. But I learned from that mistake. I did everything on the field and off, to change.

"But in fact, this is the guy who rallies the troops, who encourages us. Do not listen to everything people say."
