Brazil has an excellent team and the best players in the world play there. There is not a single player who has a slightly less level. Neymar will want to live up to expectations one day. Although the golden opportunity seemed in 2014 but then they got a beating from Germany in the semi final I can remember. Brazil will go far, but whether they become world champions depends on the form of the players. They lost to Belgium 4 years ago, but that team has not been able to live up to the high expectations in recent years. The big absentee is of course Italy at the World Cup. Although they still hope to be admitted.
Yeah, I think Brazil will end up in the final in this world cup. It's just such a good team. As you said, every player has a high level, there's no one that plays bad in there. Even on the bench, all players are top class.
In my mind Brazil will at a bare minimum will get to the semi finals, along with Argentina, Germany, and Spain.
No matter who says what, I still think that their midfield is not as amazing as people think. Yes, they have two amazing out of this world level goalkeepers, and yes their defense is not bad, and yes their offensive line is world class, all these are fine and it would be great if they had a great midfield.
But, I believe that their midfield is not good enough and they would have to work towards playing from the wings constantly, and teams could put emphasis on the wings and could stop them and ignore the midfield a bit. This is why I believe it's easy to build a strategy that would stop them, and that is why I do not think that they would play that well.
