France coach Didier Deschamps concedes Antoine Griezmann is struggling for form at Barcelona.

Griezmann has scored 32 goals and supplied 21 assists in 81 matches for his country but has struggled for form of late.

Deschamps has conceded that Griezmann's impressive record for France does not 'guarantee' him a spot in the starting XI.

"I know you're looking at the last game, but look at his stats: 81 caps, 32 goals, 21 assists. It speaks for itself," he said ahead of France's clash against Croatia on Wednesday night.

"It doesn't guarantee him anything, like some other players who could have done better against Portugal. I know his talent and what he can give to the team.

"He lacks rhythm, you know why. So, he needs a bit of time, he was much better in the second half compared to the first one. He's an attacking player but, as he runs a lot, sometimes he's an offensive midfielder."
