Real Madrid beat their manager José Mourinho's former club Inter 2-0 in the Champions League, with goals from Kylian Mbappé and Fede Valverde either side of the interval before a chaotic finish. Despite dominating possession for long spells, Inter were undone by defensive errors and a string of important saves, while goalkeeper Thibaut Courtois made a crucial stop in the 89th minute to preserve the win. The result marked a rocky but successful start to Mourinho's first Champions League campaign of his second spell in charge of the Serie A side he once managed.

Madrid's opener came against the run of play after a mix-up between Curtis Jones and Yann Bisseck let in Brahim Díaz, who set up Mbappé to finish past Josep Martínez. Valverde doubled the lead soon after when the Inter goalkeeper's failed attempt to dribble past him gifted an easy tap-in. Elsewhere in the Champions League, Borussia Dortmund beat Villarreal 3-2 despite an early scare when teenager Konstantinos Karetsas was taken to hospital with circulatory problems; Real Betis came from behind twice to win 3-2 at Lille, who had Ethan Mbappé sent off; and AEK Athens beat LASK 1-0 through a Razvan Marin free-kick.
