Xavi will be forced to make at least two changes from the first leg when Barcelona face Manchester United in the return leg at Old Trafford following a combination of injury and suspension.
The Barcelona boss had a couple of issues coming into the match at Camp Nou, and now these selection decisions have been even further complicated over the past week. One that remains unchanged, though, is that winger Ousmane Dembele remains unavailable with a hamstring problem and has not travelled to Manchester as part of the club's 20-man strong squad.
Neither have midfielders Gavi or Pedri. The former is suspended after collecting a third yellow card across the club's Champions League and Europa League campaigns when stopping Fred from counter-attacking by hauling the midfielder down with his shirt in the 73rd minute.
