Dunga has named his 23-man Brazil squad for the 2015 Copa America.
One major omission is that of Chelsea midfielder Oscar who has been ruled out after suffering an injury at training with the newly-crowned English champions.
Manager Dunga said: "We spoke with Jose Mourinho and the doctor at Chelsea. Oscar's recuperation will take time and he won't be at his best during the Copa America.
"After the Copa America we have the World Cup qualifiers, and we thought it best for him to be ready for the qualifiers."
Included in the squad is Liverpool playmaker Philippe Coutinho, Manchester City midfielder Fernandinho and Oscar's Chelsea teammates Filipe Luis and Willian.
The South American tournament takes place in Chile, staring on June 11 and concluding on July 4, featuring all 12 teams from the continent.
Eight-time winners Brazil have been drawn in Group C with Colombia, Peru and Venezuela and will take in a strong roster as they look to wrestle the title back from reigning champions Uruguay.
