Joachim Low has virtually ruled Cacau out of Saturday's World Cup quarter-final with Argentina in Cape Town.

The forward missed last weekend's defeat of England with an abdominal strain and has not trained since. Low admitted: "We have to be realistic. I don't think he will be able to play."

Argentina, meanwhile, expect to have star man Lionel Messi available despite the Barcelona frontman missing training on Thursday due to a cold.
