Real Madrid midfielder Guti has failed to recover from a muscle strain in time to feature in his side's anticipated clash against city rivals Atletico. According to Spanish daily Marca, Real medics advised coach Bernd Schuster not to field Guti as the player is yet to fully recover from the injury he sustained last month. There are more injury doubts for the Spanish champions. Malian midfielder Mahamadou Diarra is a major doubt after injuring his knee while on international duty. Dutch winger Arjen Robben may not take part in the match due to a thigh problem. Defending champions Real lie fifth in the Primera Liga table on 13 points, three behind leaders Valencia.
