Barcelona escaped with a chaotic 4-2 victory against Levante, but the second-half display was an absolute tactical disaster class. What began as a masterclass with Xavi Espart's strike and Lamine Yamal's stellar brace quickly morphed into a defensive nightmare. Flick's substitutions completely killed the intensity, allowing Levante to reduce the deficit through Iván Romero and Roger Brugué, causing unnecessary panic. While Karim Adeyemi’s stoppage-time goal eventually killed the game, allowing a 3-0 lead to turn into a terrifying thriller highlights a severe complacency that must be fiercely addressed.
