Cacau has signed a one-year contract extension at Stuttgart, despite not being expected to play again this season.
The striker has had a nightmare campaign after tearing his cruciate knee ligaments in October, before requiring surgery recently that has kept him out for a further few months.
However, the Bundesliga club have still decided to extend his stay with them until 2014, and Cacau is now desperate to return for the start of next season stronger than ever.
"Stuttgart has been my home for almost a decade and I have celebrated huge sporting successes and fantastic moments here,'' he said.
"My first goal is to get fit again as quickly as possible to be able to give it my very best next season.''
Cacau has gone on to play a total of 242 times since joining Stuttgart from Nurnberg in 2003, and director of sport Fredi Bobic believes the player's experience is a vital asset to the club.
"Cacau will be going into his 11th season with Stuttgart in the summer and that is an incredibly long time in the football world,'' Bobic told the club's official website.
"He will be able to help us further with all of his experience, so we're pleased to be able to plan with him also for the coming season.''
