As the club targets a possible treble, various factors have contributed to Barca’s comeback. They meet Atletico again in the Copa del Rey semi-finals.

With midfielder Frenkie de Jong and goalkeeper Wojciech Szczesny now established first-choice in their respective positions, Flick has made two significant changes to his team.

With Marc Casado and Inaki Pena out, Barcelona is now more effective both on the attack and defense.

De Jong appeared to have regained his confidence following a protracted sequence of inconsistency, and Szczesny has the luxury of eight consecutive clean sheets in 15 appearances.

Along with the assistance of the fitness staff, Barcelona were able to achieve a psychological as much as a physical break during the winter break.
