Yes, it is natural that Argentina is in first place, very similar to Spain, which has won back to back Euros plus the World Cup. The difference is, Spain at Euro 2008 used a different coach, while Argentina had the same coach, namely Scaloni.
Argentina's success is due to having a united team that supports and respects each other. Messi is a successful team leader, usually he is calm but since 2018 he has started to be a little more assertive in defending his friends, and his friends really respect Messi's leadership, they do anything for Messi. Argentina's other success lies in the coach, because so far Argentina has never lacked great players, it has been proven that in Scaloni's hands Argentina can achieve everything, even a great coach like Ancelotti also praised Scaloni.
So if you look at the upcoming world cup, with the performance that Argentina currently has. Argentina might be able to win the 2026 World Cup in America because the chances of a European country winning the world cup if it is held on the American continent is very small.
A coach makes a lot of difference, it can change everything, this reminds me of the Argentine team itself during the 1998/2002 world cup cycles, that team I considered one of the best Argentine teams of all time, there was Batistuta, Veron , Claudio Lopez, Samuel, Crespo, Zanetti, Ortega, that is, several of the best players in the history of Argentine football, but they were unable to do well in any World Cup, possibly due to the coach's tactical style and definitions. If Argentina maintains its standard of play, it will be the big favorite for the 2026 World Cup along with Spain.
