Dani Olmo marked his Barcelona debut with a game-winning goal in a 2-1 comeback victory against Rayo Vallecano. After being unable to register him initially due to financial constraints, Barcelona managed to include Olmo in the squad by leveraging Andreas Christensen's long-term injury. Olmo's transfer from RB Leipzig for €60 million had been delayed as the club needed to free up salary space, which they did by offloading players like Ilkay Gundogan and Clement Lenglet. Olmo had previously excelled in Euro 2024, contributing to Spain's championship win. His debut goal, assisted by Lamine Yamal, helped Barcelona maintain their perfect record in La Liga this season. Despite ongoing financial issues, Barcelona's on-field performance remains strong.
