Real Madrid opened the 2025-26 LaLiga season on Tuesday night by hosting Osasuna at the Santiago Bernabéu in Xabi Alonso’s first league match in charge of the club. The former midfielder’s inaugural lineup featured three summer recruits—Trent Alexander-Arnold, Álvaro Carreras and centre-back Dean Huijsen—while an attacking trio of Kylian Mbappé, Vinícius Júnior and Brahim Díaz led the front line. Alonso was forced to do without several regulars: Jude Bellingham (shoulder), Eduardo Camavinga (ankle), Ferland Mendy (quadriceps) and Endrick (hamstring) were ruled out through injury, and defender Antonio Rüdiger served the first match of a six-game suspension. Argentine teenager Franco Mastantuono was named among the substitutes for a potential debut. In the hours before kickoff, Osasuna confirmed it would not file a complaint over Mastantuono’s registration, quelling speculation that Real Madrid could face an allegation of improper squad listing. Spanish media reported that external legal opinions had backed the club’s procedure, which registered the 18-year-old with the reserve side while making him available for first-team duty. The match began at 21:00 local time and reached the interval goalless, with Madrid dominating possession but finding few clear openings against a deep-lying Osasuna defence. Play resumes after the break with the score locked at Real Madrid 0, Osasuna 0.
