The forward scored Germany’s second goal during their 4-1 victory over England last Sunday, but missed training today with a slight muscle problem.
The German camp has insisted that the move was purely precautionary and that they are expecting the 25-year-old to be fit to face Argentina, but it is far from ideal preparation ahead of the crucial game against the South Americans.
However, the outlook for striker Cacau is looking less promising. He missed the game against the Three Lions with an abdominal muscle strain and is now a major doubt to feature in Saturday’s last eight showdown.
Head coach Joachim Loew confirmed that Cacau will be given until Friday to prove his fitness, saying: "He is doing some light running and therapy, but today and tomorrow it will not happen [training with the team].
"So he is also doubtful for the weekend. The final decision will be taken on Friday."
After defeating Argentina on penalties at the same stage in 2006, Loew is expecting a similarly difficult task this time around, with Diego Maradona’s side impressing in the tournament so far.
"I expect an unbelievably tight match," he added. "We cannot allow ourselves any mistakes because for any mistake we make, they will punish us in an ice-cold way.
"They are the top favorites for the World Cup as they have so many players who are able to score."
