With former Real striker Roberto Soldado (six goals) netting regularly, Valencia sit third and are unbeaten at home.
Meanwhile, Barcelona will hope Real slip up and they can record what should be a straightforward win over Real Zaragoza at Nou Camp.

Real Sociedad host Espanyol, Sporting Gijon and Getafe can move further clear of the drop zone when they go head to head, while Granada and Mallorca can do likewise when they meet.
In a mid-table clash, Osasuna will be out to bounce back from their thrashing at the hands of Real Madrid when they host Rayo Vallecano, while big-spending Malaga travel to Racing Santander on Monday.
