Brazil coach Dunga says he is good friends with his Paraguay counterpart Ramon Diaz and has shared a bottle of wine or two with the Argentine, but only one of them will be in the mood to celebrate after their Copa America quarterfinal this week.

"Ramon is an experienced coach, he's enjoyed success at many different places such at River Plate and Monaco," Dunga said on Sunday after his side's 2-1 win over Venezuela in their final group game.

"He's my friend, we've shared good dinners together and good wine. He's special. As a player he had a special talent and now as a coach he's doing a very good job.
