I'd play Cavalieri; Thiago Silva, Dedé, Castán, Marcelo; Paulinho, Fernando, Ramires/Hernanes; Kaká, Oscar; Luis Fabiano/Fred/Damião.
This team is amazing, Thiago Silva is fast enough to play like we used to see Carlo's SB playing, actually Stam is slower and did a great job at this position, and he was older than Thiago is now.
Thiago Silva, Castán, Dedé and Fernando would give enough defense consistence to allow Marcelo, Ramires and Paulinho to support the attack and since Ramires and Paulinho are very good at defending too, they'd cover each other too.
Ramires/Hernanes, Paulinho, Oscar and Kaká playing in the mid together is enough to beat Spain ball possession, they're all very skilled and very clever. Whoever would be the forward, he'd feel very blessed with the amount of chances that this mid would create and Luis Fabiano, Fred and Damião are 3 great options.
Neymar, Ronaldinho, Robinho or any player like this would be just a waste of space in the squad. They're all dumb and love to do useless tricks, I mean, if Brazil has these players that are very intelligent and skilled, why should the coach count on the individual plays of these assholes?
Players like these should play for teams that are really lacking of talent and inteligence, like Milan in the last years. I mean, Carlo had Pirlo, Serginho, Cafú, Seedorf, Kaká, Rui Costa, Inzaghi, Shevchenko... there were enough amazing players with teamplay mentality, we didn't really need an Ibra. Now in the last years, what did we have? We needed Ibra's individual plays to score, otherwise we'd be screwed and the same happened when we had Ronaldinho.
Now, Neymar is an even worse version of Ibra, that is one of the best individualists in the world, why the fuck should Brazil play an worse version of Ibra?
People talk about this piece of shit like he were the next one of a list that includes Careca, Romário, Ronaldo... he's not, he's just a Robinho with a better aim. Any organized defense can neutralize him, even mexican kids did it.
