What can Barcelona learn from their Champions League defeat to PSG?

Barcelona suffered their first defeat of the campaign after losing 4-2 to Paris Saint-Germain at the Parc des Princes in the Champions League on Tuesday night. Manager Hansi Flick noted before the clash that facing PSG would serve as an important benchmark to evaluate his squad's progress, showing their current level and revealing areas requiring improvement following an impressive start.

The defeat marked an opportunity for Barcelona to assess lessons moving forward amid significant squad challenges. Flick's side competed without Eric Garcia, Jules Kounde, and Andreas Christensen, while Rodri began the game on the substitutes' bench and Dani Olmo was forced off during the first half due to an injury.
