Barcelona suffered an early blow against Atletico Madrid on Sunday with Inigo Martinez forced out of the game before kick-off.
The center-back had been named in the starting XI but pulled out at the last moment and was replaced by Andreas Christensen.
The Dane lined up alongside Jules Kounde in the heart of the Barcelona defense with Ronald Araujo on the right and Joao Cancelo on the left.
Barcelona haven’t yet said what kind of injury Martinez has picked up but will be hoping it’s not a serious issue that will force him onto the sidelines.
Martinez has played his way into Xavi’s starting XI after shrugging off an injury that saw him miss the start of the season with Barcelona.
Fortunately Xavi is blessed with a wealth of options at center-back, with Christensen slotting straight into the team and partnering Kounde against Diego Simeone’s side at Montjuic.
