France travel to the World Cup on the back of a surprising 1-1 draw with the USA in Lyon on Saturday night, but Griezmann reckons there's no need for his teammates to panic, and says their preparation for Australia starts now.

"We understand there won't be easy matches at the World Cup for us," the Atletico Madrid star told French sports daily L'Equipe.

"Australia and Peru won't be easy rivals. Denmark, too, won't be boring - we have to be prepared. We will now watch the videos of Australia, and try to beat them.

"I don't know what happened against the USA, we prepared well. But we still have time to correct mistakes. I trust this team."

Griezmann is looking to cap another spectacular club season, in which he scored 29 goals in 49 games as Atletico finished runners-up in La Liga behind Barcelona and lifted the UEFA Europa League.
