Barcelona midfielder Sergi Roberto is set to miss the Liga leaders' match against Real Sociedad on Saturday due to an ankle problem.

The club confirmed on Wednesday that Roberto sustained a sprained right ankle during the 6-1 Champions League demolition of Roma, where he was replaced by Adriano after 64 minutes.

The 23-year-old was absent from Barca's final training session ahead of the match on Friday.

There was more encouraging news for boss Luis Enrique as Andres Iniesta returned to play a full part in training having sat out the Roma match on the bench as a precaution.
