Didier Deschamps' decision to pick Mbappe ahead of Antoine Griezmann to lead Les Bleus after the retirement of Hugo Lloris was the source of much debate in France, but the coach insists that the forward is "a fantastic leader". We'll find out in Germany if that's really true, though.
France qualified for the Euros in impressive fashion, beating Netherlands home and away in their group, with Mbappe shining in both wins. However, their preparations have been less than ideal. They have performed pretty poorly in their pre-tournament friendlies, losing at home to Germany in March and being held to a 0-0 draw by Canada in their final warm-up game.
Having already lost Lucas Hernandez to injury, there are also doubts over the fitness of key midfielders Adrien Rabiot and Aurelien Tchoumani, as well as Mbappe. The man himself insists that a minor back problem and a recent knock to the knee are nothing to worry about.
He also insists that while his performances over the past season at club level were "below my standards", things are different now that he really does have everything he ever wanted. He's got the dream move to Madrid and the captain's armband for France.
There can be no excuses, then. Mbappe has got his way. He's exactly where he wants to be. PSG have already been consigned to the past and he's now looking forward to an exciting future in Spain. Consequently, he's perfectly placed to right a few wrongs at the Euros, and dismiss any doubts over his status as the best player on the planet.
Just last week, he warned, "A happy man is more likely to play well." And a vindictive man with a point to prove could be even more deadly.
