Atletico Madrid striker Antoine Griezmann says AC Milan goalkeeper Mike Maignan is transforming the game.

Griezmann insists his France teammate has changed the way goalkeeper's manage their defenders.

He explained on Telefoot, "Mike has totally changed the way of defending set pieces, he is also a great communicator on the pitch.

"Before entering the pitch he always reminds us what line to take and what position to have during corners or free kicks.

"We always listen to him carefully."
