Line-ups: Barca-Real

Barcelona revert to 4-3-3 for tonight’s clash with Real Sociedad in La Liga as Paco Alcacer replaces the suspended Neymar.

Consecutive defeats to Malaga and Juventus have forced Luis Enrique’s hand as Jeremy Mathieu makes way for left-back Jordi Alba.

Sergio Busquets is back from suspension to anchor the midfield, where he is joined by another new face in Andre Gomes.

Arda Turan, however, has failed to prove his fitness in time for the game, meaning Alcacer is shunted on the left.

Madrid’s 3-2 victory over Sporting Gijon earlier in the day makes tonight’s match a must-win for Barca if they are to keep their flagging title hopes alive.
