Barcelona meet Bayern Munich in their semi-final, while Madrid have been paired with Juventus, as the four clubs battle for a place in the final in Berlin on June 6.
Dunga’s squad are scheduled to meet at the Selecao’s Granja Comary training complex in Teresopolis on June 1, ahead of the Chevrolet Brasil Global Tour friendlies against Mexico on June 7 and Honduras on June 10.
"I hope that both are in the final. It's good to reach the squad motivated. It's good for Brazilian football,” Dunga said.
Technical co-ordinator Gilmar Rinaldi said the coaching staff will talk to the pair's respective clubs ahead of their arrival in order to assess their physical state.
"We hope that Neymar plays in both friendlies,” Dunga added.
“When we chose him to be captain we all had had an expectation of how he would behave. But since he was given the captain's armband [in August 2014], his own performances have matured at Barcelona and he is scoring even more goals.”
Neymar has hit eight goals in eight internationals since Dunga’s appointment following last year’s World Cup.
