This is my prediction to Tite's Brazil in 2018 WC.
As FIFA 18 doesn't have the Brasileirão (Brazilian Football League), I had to change my prediction a little bit and include some players who are in FIFA 18 and were more times called by Tite instead of the players I think will be called.
Here's a relation of players I had to substitute:

Cássio (GK from Corinthians), substituted by Neto.
Geromel (CB from Grêmio FBPA), substituted by Jemerson.
Fágner (RB from Corinthians), substituted by Danilo. (I do not agree with this one).
Arthur (CM from Grêmio FBPA (recently he was bought by Barcelona, but will stay at Grêmio until the end of 2018)), substituted by Anderson Talisca.
