Barcelona left-back Jordi Alba could miss his side's Spanish La Liga visit to Real Sociedad on Saturday due to a hamstring strain.
Alba suffered the injury in Barça's 2-0 win away to Manchester City in the first leg of their UEFA Champions League last 16 tie on Tuesday.
"After arriving at the training ground, tests carried out have confirmed a strain in his right hamstring," the club said in a statement. "His recovery will determine whether he is available for the next game, which will be against Real Sociedad at Anoeta on Saturday."
Barça are currently in a three-way tie at the top of La Liga with Atletico Madrid and Real Madrid on 60 points.
