The names on the list are simply dreadful, I don't know how else describe them. Of course it's not Ancelotti's fault, those are the players Brazil is currently producing. Once they had Roberto Carlos and then Marcelo, now there is Alex Sandro. They used to have defenders like Lucio and Thiago Silva and now the best one is Marquinhos, which is very good, but not as good the the others I mentioned. Midfielders? Players like Juninho Pernambucano often times weren't even called because they had better players, now he would be by far the best midfielder. And maybe it's better not to talk about the strikers: the fact that a 33 year old Neymar is the best attacking player they have speaks volume. Let's see if Raphinha keeps playing like he did last season.
Carlo Ancelotti has what it takes to do well, we don't understand some of his choices but he certainly had his reasons.
He has successfully coached teams of the calibre of Real Madrid for many years, and i think he will be able to do well with Brazil too.
I am very sure of it.
