What's with Dunga and 'Dinho?

Not the unfamiliar topic.
"Ronaldinho is officially back to his best!The Seleção now needs him!"
So,say  most of the fans of the beloved game.Except Dunga,oh well,the coach.

Dinho was snubbed by Dunga,quiet rightly,after his epic loss of form since moving to AC Milan.And since then,Brazil,under the new coach Dunga,has started playing a 'different' style of football,not the flashy Samba style we've seen and enjoyed for years.And yes,it has been successful till now and the Brazil,are arguably one of the favorites for the World Cup 2010.
