Dani Olmo marked his Barcelona debut with a pivotal goal, securing a 2-1 comeback victory against Rayo Vallecano. Unable to play earlier due to La Liga’s financial regulations, Olmo was finally registered after injuries and transfers facilitated his inclusion. Introduced at halftime, he revitalized Barcelona, leading to Pedri’s equalizer and scoring the decisive goal in the 82nd minute. This victory maintains Barcelona's perfect start to the La Liga season with three wins from three matches under new coach Hansi Flick. Despite the win, concerns arose over a potential serious injury to 17-year-old Marc Bernal. The victory places Barcelona at the top of the standings with nine points.
