Alexis Sanchez is a doubt for Barcelona's 219th Clasico meeting with Real Madrid, after the Chilean picked up a leg injury in the midweek Champions League defeat at Chelsea.
Pep Guardiola has no other injury concerns, with long-term absentees David Villa, Andreu Fontas and Eric Abidal the only players unavailable.
Gerard Pique should make a return to the Blaugrana defence, with Carles Puyol filling in at left-back in place of the versatile Adriano.
Real Madrid could recall Marcelo to the starting line-up, while it remains to be seen whether his compatriot Kaka - dropped to the bench in the last two matches - regains his place in the team.
Xabi Alonso is available after serving a one-match domestic ban, but Ricardo Carvalho (thigh) and Lassana Diarra (hamstring) are unlikely to be involved.
