Real Madrid kicked off their 2025-26 La Liga season with a hard-fought 1-0 victory against Osasuna, thanks to a second-half penalty from Kylian Mbappé. The match, held at the Santiago Bernabéu, marked a successful debut for new coach Xabi Alonso, who took over from Carlo Ancelotti following the latter's appointment as Brazil's national team manager.

Mbappé's decisive moment came in the 51st minute when he was fouled in the penalty area after a skillful run and cutback. He coolly converted the penalty, placing a low shot into the right corner while the Osasuna goalkeeper dove the opposite way. The Frenchman, who was the top scorer for Madrid in his debut season, showcased his importance to the team by securing the win in a match where Madrid dominated possession but struggled to break down a resilient Osasuna defense.

Alonso started the match with three new signings: left-back Álvaro Carreras, right-back Trent Alexander-Arnold, and central defender Dean Huijsen. The crowd at the Bernabéu welcomed Franco Mastantuono, a teenage forward, who came off the bench and nearly doubled the lead with a chance late in the game. However, his effort was saved by the Osasuna goalkeeper, keeping the scoreline tight.

Osasuna's Abel Bretones received a straight red card in stoppage time for a foul on Madrid's Gonzalo García, further complicating their efforts to push for an equalizer. Despite the defeat, Osasuna's midfielder Rubén García acknowledged their solid performance, stating that Madrid deserved the victory based on their overall dominance in the match.

With this win, Real Madrid starts their campaign on a positive note, earning three points, while Osasuna will look to regroup in their next match. As the season progresses, Madrid aims to reclaim the La Liga title after finishing as runners-up to Barcelona last season, while Osasuna seeks to improve on their ninth-place finish.
