Brazil manager Dunga will be among the supporters in the stands when Paris Saint-Germain take on Chelsea on Tuesday night.
Dunga will be keeping a close eye on many of the players on show with several being eligible for the Seleção.
Thiago Silva, David Luiz, Marquinhos, Ramires, Oscar and Willian are all expected to play a part in what will be one of the first of several huge Champions League games this week.
“I will be watching each player closely,” warned Dunga who was speaking at the Carnival of Rio.
Brazil have won every single match since Dunga took charge last year and are growing in confidence ahead of the Copa America.
