Barcelona have been handed fresh concerns with Frenkie de Jong and Eric Garcia ahead of Thursday's Europa League playoff second leg with Napoli.
The duo were both substituted early in the 4-1 La Liga win over Valencia at the weekend, although they are not nursing anything serious and are battling to be fit for the midweek contest.
Sergi Roberto, Ansu Fati, Samuel Umtiti and Alejandro Balde are all set to miss this one for the visitors, who will have Gerard Pique available again after a domestic suspension, while Memphis Depay and Clement Lenglet have not made the cut.
Pique is sure to take the place of Garcia in the backline alongside Ronald Araujo - who was not present in the first leg - as Serigno Dest continues at right-back in place of the ineligible Dani Alves.
If Xavi decides that De Jong is not quite fit enough to start the second leg, teenage starlets Pedri and Gavi could both feature from the first whistle alongside the veteran Sergio Busquets.
Ferran Torres was guilty of missing two gilt-edged chances to win the first leg for Barcelona, but having scored the penalty to make it 1-1, his place in the final third is not at risk.
Torres should be one of three recognisable faces from the Premier League in the attack, as Adama Traore and Valencia hat-trick hero Pierre-Emerick Aubameyang seek to propel Barca into the last-16.
Barcelona possible starting lineup: Ter Stegen; Dest, Araujo, Pique, Alba; Pedri, Busquets, Gavi; Traore, Aubameyang, Torres body check tags ::
