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.
France have a very strong team but it does not guarantee titles for them. They won World Cup 2018, failed in Euro 2020 and played well in World Cup 2022. They have a very golden generation that can help them to win more titles in Euro and World Cup.
England are a bit far behind France and they need to win one title to be recognized. A runner up in Euro 2020 is not enough. They can hope that a treble winning of Manchester City including Champions League will help their national team gain big success. We see Spain, Germany got a lot of positive impacts from their club success.
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 will have to face with uncertain future without Messi. He does not want to play for Argentina in another World Cup and even he wants, Argentina have to prepare for a future non-Messi future.
