Barcelona have received a complaint from Atletico Madrid filed with FIFA over allegedly tapping up Julian Alvarez, a source from the Catalan club told AFP Thursday. Argentina striker Alvarez said during the World Cup it would be “the best thing for everyone” for Atletico to let him leave, amid strong Barca transfer interest. Atletico believe Barcelona made prohibited contact with the 26-year-old attacker to encourage him to force his departure. Spanish media reported Atletico have also filed a complaint to the Spanish football federation (RFEF), but the RFEF did not respond to an AFP request for comment. Alvarez joined Atletico from City in 2024 for a deal worth up to 85 million euros.
