Brazil big favourites imo but we will see, there are always surprises in this tournament after a long season.
Brazil team is full of stars, though I would really miss neymar but willian is replacing him, Let's hope willian put a a good efforts.Midfield is strong of Brazil, Casemiro, Arthur should make some key passes.Firmino, Jesus, Richarloson would play in forward position, I'm expecting a lot from them.I thought vinicius should join the team after Neymar departure. Tite knows better than me, I believe in him.
Surprises will always be present in every tournament and here I don't favor one team because I'm not sure the big team with big players can perform well throughout the tournament. So I will only predict when the match will begin.
