After Les Bleus' 4-0 victory at the Parc des Princes last week, Giroud complained that he did not get as much service from his teammates as he would have liked, after his brace edged him closer to Thierry Henry's France goalscoring record.
Mbappe reportedly wanted to publicly answer Giroud as he appeared to have been angered by his teammate's comments, but manager Didier Deschamps decided to take the matter into his own hands to draw a line under the situation.
However, during a pre-match press conference, Mbappe said: "I spoke with Olivier Giroud. Everyone knows what happened. It is true that I was a little affected by it. But we are not going to make a big deal about it because we are here to represent France, that is the most important thing.
"It is more that he said it publicly than the fact that he said it. I saw him in the dressing room and he didn't say anything to me. He expressed a feeling that I have had 365 times during a match."
