Brazil manager Dunga has told former World Player of the Year Ronaldinho the door is still open for a return to the national side.
The AC Milan forward was left out of Brazil's squad for the Confederations Cup in South Africa as they bid to win the tournament for a third time.
Ronaldinho has suffered indifferent form since his move to the San Siro from Barcelona, scoring 10 goals in 32 outings in his first campaign.
Wayward form for both club and country towards the end of last season prompted Dunga to omit him from his squad for the Confederations Cup, which acts as a dress rehearsal for next year's World Cup.
"I would like him to come back," said Dunga. "But whether he will come back I don't know.
"I think you must address that question to him directly. He obviously has that responsibility on his shoulders, it depends more on him than on me, but I would like him to come back."
Upon announcing his players for the tournament, Dunga revealed he would not pick the Milan star until he recaptured the type of form which once made him the best player in the world.
In March, the 29-year-old was ridiculed for a poor performance as Brazil drew 1-1 with Ecuador in a World Cup qualifier and he has made just one appearance in the yellow shirt since.
Despite the absence of one of football's biggest stars, the national team have been in impressive form in South Africa, netting 11 goals en route to Sunday's final against USA.
Despite the form, which includes a 4-0 drubbing of World Cup holders Italy, Germany legend Franz Beckenbauer has suggested the South Americans are not equipped to win a sixth Cup next year.
But Dunga, who captained his country to their 1994 triumph, disagrees and highlights their attacking ability as a strong point.
"Anyone can have an opinion," said Dunga. "So let's just look at the number of goals we scored here.
"We had the best attack in the group stages and scored 10 goals and you can't argue against the numbers and the facts."
