Sergio Busquets is a major doubt for Barcelona's make-or-break clash with Valencia after he suffered a gash to his knee in Saturday's win over Real Sociedad.
The defensive midfielder's injury stretches an already long sick list at Camp Nou, with Andres Iniesta, Pedro and David Villa all sidelined.
Coach Pep Guardiola could retain Cristian Tello in attack after the youngster impressed against Sociedad, while Xavi Hernandez, Gerard Pique and Alexis Sanchez are all likely to be restored to the starting lineup after being rested in the weekend fixture.
Valencia coach Unai Emery looks set to recall Ever Banega and Jonas to starting XI after the midfield duo were rested for Sunday's goalless draw at Atletico Madrid.
Los Che need to score to have any chance of progressing to the final, as Carles Puyol's header in the 1-1 draw at the Mestalla last week gives the Catalans the advantage on the away goals rule.
