Out of 24 players there are only these 10 who actually play for big teams. I understand that Ancelotti wants to try different solutions and players but, for me, the squad is kind of sad. Ancelotti has a tough job ahead because he must obtain results that, on paper, are beyond this team's possibility because for sure Brazilian people expect Brazil to win the World Cup (as usual) but there are several teams way better than them.
I believe that since qualification is guaranteed, he wants to get to know these players better, since he already knows the others and has worked with them before
Ancelotti even gave an interview (but I only have the link in Brazilian Portuguese:
https://ge.globo.com/futebol/futebol-internacional/noticia/2025/08/25/ancelotti-diz-que-convocou-paqueta-para-conhece-lo-melhor-aproveitar-desse-tempo.ghtml) where he said that he called up Lucas Paqueta to get to know him better, since he has never worked with him
This is an indication that he wants to test as many players as possible in these matches, which theoretically are less important for Brazil
I also really like the team's independence without the big names; it creates new leaders within the team and allows them to have more synergy with each other. But obviously, without these key players it will be more difficult, but as he himself said, they are already qualified and can very well try new things.
It may even be in lesser-known teams like this one that potential players emerge who could be VERY good but who were overshadowed by the bigger names that are usually called up
I'm very curious to see João Pedro from Chelsea
