Barcelona faces major setback with key player set to miss entire season due to injury
Hansi Flick's men remained at the top of La Liga as a result of this win, four points clear of second-placed Real Madrid.
However, it was not all positive for the Catalans, as they lost one of their vital players to a potential season-ending injury.
Stegen set to spend a long time on the sidelines
Barcelona goalkeeper Marc-Andre ter Stegen is expected to be sidelined for up to eight months after the 32-year-old sustained a knee injury during the team's victory over Villarreal.
The injury to Ter Stegen is a major blow, as the German goalkeeper has been a key figure for the club since joining from Borussia Monchengladbach in 2014, winning five La Liga titles and a Champions League.
Pena to step in for Stegen
Inaki Pena, a 25-year-old academy graduate, is expected to fill in for Ter Stegen during his absence. Pena has limited first-team experience but will be called upon to deliver consistent performances.
The goalkeeper has conceded 39 goals in 22 matches for Barcelona keeping 5 clean sheets so far.
