Barcelona has suffered a significant setback with the news that one of their important players is set to miss this rest of the season.
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.
