Les Blues were favourites for the tournament after winning the World Cup three years prior, but they cam unstuck against Switzerland in the round of 16.
The Paris Saint-Germain star came in for a lot of criticism after his miss the penalty shoot-out handed Switzerland victory.
Le Graet has revealed that Mbappe was upset that no one from the federation defended him after their elimination.
“We met for five minutes in my office. He was angry, he didn't want to play for the French team any more - which he obviously didn't mean.
“You know how it is, he's a winner, he was very frustrated, like all of us, by the elimination.
“He's so media-friendly. He's a great guy, much more collective than people think.”
