After the previous World Cup, everyone thought that France would be at least among the winners of the next Euro, but in the end they lost right away in the 1/8 finals. Such short tournaments are always random, but the fact is that we are now in an era of French dominance and they will be the biggest favorites to win the European Championship.
I am not sure whether the French will be the favorites to win Euro 2024. I could see a lot of vulnerabilities in their performance during Qatar 2022. IMO, Spain and England are far better teams, although they couldn't perform well during the last world cup. Regarding France, I always had this opinion that their players are overrated. Kylian Mbappé, Paul Pogba and Karim Benzema are good players and maybe some of the best in the world. But they don't know how to play as a team and the team cohesion is lacking in the French team whenever they play.
I don't know where you get such subjective observations from, in my opinion (also subjective) the French team plays very unitedly. Spain, England (and Germany and defending champions Italy) are good teams, but objectively France is doing better and, judging by the individuality of the players, they are also stronger. In my opinion, France looks better both in terms of names and in terms of play.
There is no need to discuss about favorites or which is a better team between the top teams in Europe. All of those teams have what it takes to win the title and it doesn't matter which team is 5% better when one red card or one penalty in the game can decide the winner and send another team home. That's the beauty of this kind of competition where every team has to give their best performance in every game.
