"Kylian is putting in some great performances at the moment," Deschamps said at a media conference.
"He is scoring goals and is in excellent form. Seeing as he is still very young, he obviously still has room for improvement. But it is quite remarkable what he has been doing, how calm and mature he is. He got here with a big smile on his face.
"There is no reason why he could not start. The fact that it is his first time with the national team does not mean he cannot start. But we should not move too fast.
"That I called him up does mean that he will play at some point, though. All the players who I called up should have the ambition to start."
