Stuttgart veteran Cacau has extended his stay at the club into an 11th season by signing a one-year contract extension.
Germany and Stuttgart striker Cacau is likely to miss three months of action, having torn his medial and cruciate knee ligaments during training.
Cacau believes his lack of playing time in the Bundesliga cost him his place in Germany's UEFA EURO 2012 squad, and is open to leaving Stuttgart.
Cologne maintained their battle to avoid relegation from the Bundesliga with a 1-1 draw at home to Stuttgart, who equalised through Cacau after Slawomir Peszko's opener.
Following their 1-0 defeat to Stuttgart yesterday, Nuremberg director of sport Martin Bader feels his side were unlucky to be on the losing side and thinks they have shown why they have already accrued 31 points.
A solitary goal from Cacau saw Stuttgart ride out their luck and beat Nuremberg 1-0 to put them very much in the mix for a UEFA Europa League qualification place.
