Brazil lacks midfielders and Defenders? Are you kidding me, my friend, or do we watch football from different planets? I am no fan of Brazil, but they have more than enough talent to dominate once again if they are really organized.
Ancelotti is a tournament kind of coach, and most of his success has come from tournaments. I believe he will elevate Brazil and probably take them back to the old days.
Brazil's squad is very strong. There are many talented players in the attack, midfield and defense. And most of the Brazilian players are in renowned clubs in Europe. So there is no reason to think that the Brazilian squad is weak.
In the last few years, we have seen that Brazil's main weakness is that their match strategy was not good. At the same time, the bonding between the players was weak. Brazil really needed an experienced coach like Ancelotti. Only an experienced coach like Ancelotti can change the entire scenario of Brazil.
Ancelotti is well aware of the style of play of Rodrygo and Vini. He will probably build his match strategy around Raphinha, Vini and Rodrygo.
