Barcelona defender Gerard Pique scored the only goal of the match as they beat Dynamo Kyiv 1-0 to record their first victory in this season's Champions League.
This was the defender's 16th Champions League career goal, pulling him level with former Real Madrid and Brazil defender Roberto Carlos at the top of all-time scoring defenders in the competition.
The win saw Barcelona move third in their group, a point behind Benfica. Bayern Munich, who beat the Portuguese side lead the group on nine points.
Ronald Koeman's side has underperformed this season both at home and in Europe, with pressure piling on the Dutchman.
