Since when Dunga arrived in Brazil's national team, Luis Fabiano has been the leading scorer under his management with 19 goals in 26 matches. Sevilla's striker also saved Dunga's head a coulpe of times when he was bouncing to get fired.
Even though he has done so much, and has his guarenteed spot in the team's offense, Fabiano has not been dealing with his bests performances in Brazil and Sevilla for the last few months.
Luis Fabiano went through a season with a lot of injury problems an he failed to score in his last five games with Brazil. The last time he scored a goal was against Venezuela in the last round of the south-american World Cup qualifiers.
Personnaly, I don't believe he isn't going to score any goals in this World Cup against such weak opponents. In my opinion, Brazil has probably the easiest group stage in South Africa and that may blind some mistakes.
