Arjen Robben and Gabriel Heinze are certain absentees from Real Madrid's trip to Espanyol after suffering injuries whilst on international duty, the Primera Liga holders said on Friday. Dutch winger Robben faces up to six weeks on the sidelines due to a thigh injury sustained during Holland's 2-0 victory over Slovenia in the Euro 2008 qualifiers. Argentinean left-back Heinze will be out of action for two weeks as he tore a muscle in his left thigh during his country's match against Chile in the 2010 World Cup qualifiers last Sunday. Brazilian midfielder Robinho is also likely to miss Espanyol match in the league on Saturday after arriving late following Brazil's thumping 5-0 win over Ecuador. However, coach Bernd Schuster will be boosted with the news that Guti and Fabio Cannavaro have been passed fit to take part in the game despite suffering minor knocks in training.
