Kaka admits he was worried he wouldn’t get another chance with Brazil.
The 33-year-old was a surprise inclusion in Dunga’s squad for this month’s Chevrolet Brasil Global Tour double-header with Costa Rica and USA, having not appeared for the Selecao since October 2014.
And the former Fifa World Player of the year says he is ready to grab his unexpected second chance with both hands.
“I didn’t not know if I would get another chance in the squad,” he told reporters in New Jersey.
“But I knew that if the chance came I would have to be prepared. And I am.
“I'm fine physically. It has been a long time since I had physical problems,” added the veteran, whose time with Real Madrid between 2009 and 2013 was dogged by persistent injury.
“I feel confident technically and I am prepared for these games. If I have a chance to play you will see how much I can still contribute to the national team.”
