Kickoff is Thursday, 4 September at 20:45 local at Sofia’s Vasil Levski National Stadium, with Serbian referee Srdjan Jovanovic appointed. In Spain the match airs on La 1 and streams on RTVE Play, while Argentine listings indicate exclusive streaming on Disney+ Premium. Spain, the reigning European champions, arrive on a sustained unbeaten run in official matches and are heavy favorites, with reports tipping starters such as Rodri and Lamine Yamal. Gavi, Yeremy Pino and Fabián Ruiz are out injured, leading to call-ups for Aleix García, Jorge de Frutos and debutant Jesús Rodríguez. Bulgaria enter under coach Ilian Iliev with few recent wins and a low FIFA ranking, and Group E sends only the winner directly to the World Cup with the runner-up bound for a playoff.
