Yeah, he was approached by our Federation and it was said that he would be interested in taking the reins but only after seeing his contract with Chelsea through. We should have accepted Guardiola's offer last year.
A lot of things can change in 4 years. This is not a bad generation - except maybe offensive wise; although there's this guy from Santos who seems to be the number 9 we need, look up Gabriel; - by any stretch, what happened against Germany was a casualty caused by many factors... Now, did that team even try to look like any Brazil of the past in the whole tournament? Absolutely not.
Still It's not that the Brazilian talent well has dried up or that suddenly all the players in that team became bad. There were good players there, maybe mentally weak not prepared to that kind of pressure - at home - or most likely what we saw, a coach that failed to fix that midfield. We're not Spain or France, a one-hit-wonder or anything like that. It could take another 20 years but Brazil will bounce back.
Not too long ago Argentina was beat 6-1 by the great Bolivia, 3 years later they reached a WC final playing horrible football. And honestly, had they better strikers they would have won that title. So don't underestimate what a good coach could do with the right players.
It's funny cause i've always thought 2018 would be our World Cup, when players like Neymar, Oscar, Coutinho, Marquinhos, etc... Will be Euro-experienced enough to handle a competition of that caliber. Of course, we were at home so it wouldn't stop me believing that we could do it now but we all know what happened.
