Barcelona forward Lionel Messi is racing to recover from a hamstring strain in time for the crunch encounter against Paris Saint-Germain at Camp Nou.
Cesc Fabregas is likely to be preferred in attack if Messi fails to return, while Pedro is also in contention for a starting berth after recovering from a calf injury.
Blaugrana boss Tito Vilanova may deploy either Sergio Busquets or Alex Song in central defense in place of the inexperienced Marc Bartra to counter the attacking threat of the visitors.
PSG captain Thiago Silva is expected to play despite missing the weekend win at Rennes with a bruised knee.
Thiago Motta (groin) and Alex (thigh) should also be fit, but Blaise Matuidi is suspended after picking up his third booking of the competition in the first leg.
