I was really surprised by Zanetti and Cambiasso, they've both been in really good form. Cambiasso has been excellent in the Champions League this season.
Nasri was a shock too, but not Benzema. He's had a poor season for Real Madrid and I think he needs to get out if he wants to revive his international career.
As for Pato I'm not sure. I heard he's had a lot of problems at international level and never really performs that well for them, which is exactly the reason Adriano was dropped for this year and I think Dunga made an excellent choice with that. The same goes for Ronaldinho, who has been pretty average for a few years now.
