“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.
“It’ll be a finely balanced match. It’ll be like a final.”
The two sides will meet in the southern Chilean city of Concepcion next Saturday in a repeat of the 2011 quarter-final, which Paraguay won on penalties after holding Brazil to a goalless draw.
