Considering how well they have done so far, I am guessing that everyone is favoring France easily, yet the biggest threat they have is that a lot of their players are young as well, not all of course but plenty of young stars in that team which means that they are going to be favorites for many upcoming tournaments, at least until 2030 world cup.
In the end, France and England has proved everyone how good they were but they could meet again like last time and that could cause them not to face at finals, and that would be a shame but it gives another team a chance. If you meet either of them on the finals, it doesn't matter which team is playing, at the final game it's just one win takes it all situation and anything could happen.
There is no doubt that France is the strongest team in UEFA at this point. And only England can give them some sort of a competition. But there is no guarantee that France will be able to maintain their dominance in the long term. We all saw what happened during the 2022 FIFA World Cup finals. Argentina completely dominated the match for the first 80 minutes, as there was hardly any co-ordination between French players. Having good players alone will not work, if the players doesn't bond together as a team.
Argentina is a great team developing itself in these last years with Messi as an even greater team,they lost the final of the World Cup in 2014 and they won it in 2022 so their form was excellent and it was the best team of the whole World Cup.In the Euro though France yes it is the most promising team to win the Euro but let's not forget Germany who is the host and is playing in front of their home fans willing to ask a forgiveness for what they achieved in the last years and wanting to be one of the most prestigious teams like they deserve too,then of course England is the best team,let's also not forget a very young age as a team for Spain who are growing together,I think it will be disputed between these teams the Euro 2024.
