Griezmann didn't have much choice because even though he probably did even better than Mbappe at the World Cup, but he is more of the past and Mbappe is obviously the future. Therefore, if he had aggravated the conflict, then it would have been decided not in his favor, therefore, the reconciliation of the players in this situation is simply logic and not someone's specific merit. But in general Deschamps is giving a result and France are top 1 favorites to win Euro24, let's see how they can realize their chances.
Griezmann was either going to accept it or retire from the French national team, he does not want to retire yet so he had to accept the decision even though he didn't agree with it and neither did i, Mbappe shouldn't be the captain, even though he is the best player in the team, there are other senior players that deserve to be captain ahead of Mbappe, but the decision is already made and cannot be changed. France are surely the favorites for any tournament they are in right now, and they are favorites for the Euro next year and will probably win it, but anything can happen though.
By the way, the gap between France and the other two competitors is not so great:
In general, this is probably a fair assessment, the only thing that is clearly out of place is Spain - it seems to me that they showed dull football at the World Cup and it is unlikely that anything will change in two years. I don’t understand why they are better than the Netherlands or Italy.
