Surely has to be the squad Brazil takes for the 2015 Copa America. Cassio has been in good form for Corinthians, so it's time to see whether he can be the one to be between the sticks in Russia since Brazil's other goalkeepers are getting up there in age. Move David Luiz to midfield since he seems to love bombing forward and his runs will be less disastrous from there. Danilo is the best young right back Brazil has, and it's time to throw him into the deep end so he can learn. Filipe Luis should've gone to Brazil, and he deserves to start ahead of Marcelo especially with him being in unreal form for Atletico these past two seasons. Take out Hulk and Fred and insert Lucas and Firmino by having them flank Oscar. The front four of Neymar, Lucas, Oscar, and Coutinho will be dynamic with all four switching throughout the game.
It should be the majority of the squad that goes to Russia in 2018 with Marquinhos replacing Dante, Lucas Piazon replacing Hulk, some center mid such as Fernando replacing Fernandinho, and Rafael or Mario Fernandes replacing Dani Alves.
