The 22-year-old Liverpool star is back with the Selecao after a four-year absence and thanked club manager Brendan Rodgers for aiding his development into a Premier League star
On Tuesday, the 22-year-old was named among a host of new faces as coach Dunga selected his first squad since succeeding Luiz Felipe Scolari for his second spell in charge of the Selecao.
And after missing out on a place at the World Cup earlier this year, the former Corinthians and Inter man is desperate to make the most of his second chance.
"I'm very happy. What great news I received today," he told EPSN Brasil.
"I had high hopes. I was sitting here with my eyes on the computer and clinging to my phone. Some friends and family called me. I was hoping to be part of the list, yes. Thank God I got the chance and now I hope to do my best."
The midfielder’s one and only cap arrived back in 2010 against Iran, but he will now return to the squad after a four-year absence thanks to his fine form since joining the Premier League club last season.
And Coutinho thanked club coach Brendan Rodgers for his international reprise, insisting he has matured since his last call-up and is ready to cement a place in Dunga’s new-look Brazil.
"When I had my first chance I was very young," he continued.
"I had just arrived at Inter and football here in Europe is very different from Brazil. I wasn't used to it yet.
"Nowadays I feel much more prepared, more experienced. I've played enough games here. I feel more ready now than I was the last time.
"Brendan Rodgers has a huge part in my development. He's very important. Since I got here he's been helping me so much, always trying to help me evolve and improve."
Brazil begin life under Dunga as the Gillette Brasil Global Tour continues with clashes against Colombia and Ecuador next month.
