Real Madrid manager Bernd Schuster will have to do without Argentinean defender Gabriel Heinze who will be out for the next five weeks with a knee injury. A statement on the club's website said that the 29-year international player will be submitted to further tests later on. Heinze had to quit last Sunday's clash against Real Zaragoza, 2-0, in the 17th minute. Miguel Torres, who replaced him during the game, is set to fit in the Merengues back four until his recovery.
