The forward made the move to the Nou Camp from Atletico Madrid last year but has struggled to make an impact and is now being played out of position by new manager Ronald Koeman.
Deschamps will team up with the player during the upcoming international matches and had his say on the situation.
He said of Griezmann: “I'm talking to him and I'll see him later. I am sure he is not happy with this situation.
"I don’t interfere with the use of my players in other clubs, be at Barca or anyone else. Antoine is playing on the right there at the moment. It's true that Koeman said, and told him, that he did not understand that he was used to playing in a more central position. But Antoine must also adapt today."
Deschamps - who lead France to World Cup glory in 2018 - feels that Griezzmann is at his most effective at the "heart" of a match.
He explained: “For me, he is still more effective when he is in the heart of the game, when he is able to touch the ball a lot. In that position, he has the possibility to come and help in the midfield too.
“He doesn't have the ability to take the ball and beat opponents on the wing like others. He needs to touch the ball a lot and he is smart in his movement.”
Deschamps also suggested that France will deploy Griezmann in a more orthodox position.
He said: “We must do what’s best, taking into account the different situations at Barca, the system and the players. Antoine never complains, but to give his full potential it's always better when a player is in his best position."
