Fair enough on Dunga - the truth is Brazil's style has infuriated me for a good while, regardless of the coach. And in Brazil, anything other than a WC win is a complete failure. Mano was probably the best coach since Scolari, and wasn't even much different than him.
Palmeiras had a really weird season. They won the Copa do Brasil, and subsequently got into next year's Libertadores. Though, by putting all their eggs in the Copa basket, they got into the relegation zone in the league. Felipão left, and now they are relegated.
His definite high points are Brazil and Portugal, which gives me hope he can achieve success again managing a national team. Clubs are obviously a different animal, since you have to work with the players you get. Now, he gets to choose the players to suit his style - and with the talent level available, and home field advantage, expectations are at an all-time high. So, it's good to have a coach who's been there before - the pressure shouldn't be so overwhelming for him.
