The naturalised Stuttgart striker is not fazed by the idea of facing the country of his birth, and is raring to go in what will be an 'extraordinary' match on Wednesday night
The 30-year-old has spent his entire career in his adopted nation, and has been a regular name in Joachim Low's squad since his debut in May 2009, but says he is relieved to have recovered from surgery on his groin problem in time for the friendly.
"I'm very happy to be a part of this, it was a tough season [last season] but the operation went well and I'm fit now," said Cacau at a press conference for the match.
"To be part of the preparations and [speak] here today for the German national team, for such an important game, it is a huge honour because we're playing against Brazil."
Cacau showed no fear when talking about playing his native Brazil, viewing it as a proud moment in his career.
"It's a dream come true to play against the country of my birth and it's going to be an extraordinary game, I can't wait for it any longer," confessed the striker.
"A lot of people have asked for my feelings [on the match] but what can you say, I can't describe it but it's going to be exceptional and I'm very happy to be a part of this team."
Germany host their South American opponents on Wednesday night.
