FC Barcelona secured a 2-1 victory against Valencia at Mestalla, showcasing young talents like Lamine Yamal and Pau Cubarsí in the starting lineup. Notably, Marc Casado made his first league start, while Marc Bernal debuted for the first team after a season with the reserves. Hansi Flick's strategy emphasized youth, as Pau Víctor and Gerard Martín also saw their first professional minutes during the match. Earlier, Barcelona confirmed the registration of Pau Víctor and three other players ahead of the game, despite some initial confusion regarding Victor's registration status. The club is still working on registering Dani Olmo and Vitor Roque, who remain unregistered. With injuries affecting key players, the emphasis on youth is a significant shift for Barcelona under Flick.
