Barcelona coach Hansi Flick emphasized the need for better defense after his team conceded a last-gasp winner against Champions League holders Paris Saint-Germain (PSG), resulting in a 2-1 defeat.

• PSG secured their victory with a goal in the 90th minute from Goncalo Ramos at the Olympic stadium.
• Coach Flick admitted that PSG were operating on a higher level and that his team was below its best, stating, "There is no point in saying we are on the same level."
• Barcelona was previously knocked out of last season's Champions League semi-finals by Inter Milan, conceding seven goals across two legs.
