The hosts needed less than six minutes to open the scoring against Hansi Flick’s side and then added a second on 17 minutes following another quick break.
The goal means that Barcelona are now on their worst run without a clean sheet for over a decade. The Catalans have conceded in their last nine games in a row and let in 14 goals during those matches.
It’s a record that Flick will hate to see and will no doubt bring more scrutiny on his famous high line.
The Poland international is yet to keep a clean sheet since returning to the starting XI following Joan Garcia’s injury, and he may be set to return to the bench soon with Garcia closing in on a comeback.
