Barcelona paid a price for qualification to the semi-finals of the Copa del Rey after losing both Andres Iniesta and Alexis Sanchez during last night's clash with Real Madrid. Spain midfielder Iniesta limped off in the 29th minute and examinations revealed he had a torn muscle in his left leg. Further tests will be held today to determine the extent of the injury and an estimation of the player's recovery time. Alexis was substituted 11 minutes from full time with a shoulder injury and is expected to miss between one to two weeks. The game at Camp Nou finished 2-2 with Barcelona going through 4-3 on aggregate.
