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 line-up 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.
| DID YOU KNOW? |
- Barcelona are the most successful club in Copa del Rey history, having won it 25 times and finishing runners-up 10 times.
- The Catalan giants haven't lost a competitive match at Camp Nou since September 2010.
- With a seating capacity of just over 99,000, Barcelona's Camp Nou is the largest stadium in Europe.
- Valencia have won just once in their last nine away games in all competitions.
- Los Che haven't won at Barcelona for more than eight years, with their last victory coming in October 2003.
- Roberto Soldado (pictured) is the Mestalla club's leading scorer this campaign with 20 goals.
After a series of sub-par displays in recent weeks that has seen them lose ground on Real Madrid in the league, Barcelona will be determined to make sure that they do not get beat here. The visitors are going through a poor run of results themselves, and it is difficult to see them turning it around at Camp Nou.

Barcelona 2-1 Valencia
