The reigning world champions recorded a comfortable 3-0 win over Bulgaria on Tuesday, in the nation's final pre-tournament preparation match ahead of the European Championship, which gets underway this weekend.
However, tensions appeared to boil over after the encounter when Giroud, who scored twice for Les Bleus after replacing the injured Karim Benzema, appeared to accuse strike partner Mbappe of not passing to him.
"If you received the ball after each time you called for it, it is always the same," Deschamps said.
"The attacker says, 'I am making runs, but it's on the midfield.' The midfielders will say that it is on the attackers. Sometimes, the pass isn't forthcoming, sometimes it is down to the movement. But this is not a stigmatisation of Kylian or whoever."
However, while Deschamps was not picking sides, former France international Johan Micoud spoke out against Mbappe, whom he subtly accused of playing for himself and not for the team around him.
"It's becoming embarrassing. And even when he came off..." Micoud said. "You have just played two warm-up matches, it has gone very well and when he came off the pitch it was as if the team had lost 4-0. At some point, it is not all about you."
