The opening night of the Champions League league phase delivered six official results and three 3–2 contests, with Premier League and La Liga clubs immediately taking centre stage.
Real Madrid began their European season with a 2–1 win over Inter at the Bernabéu. Kylian Mbappé and Federico Valverde scored for the hosts before Carlos Augusto reduced the deficit. Reuters reported that Madrid capitalised on two Inter mistakes, with Thibaut Courtois playing a decisive role in protecting the lead.
In Portugal, Manchester City beat Porto 2–0. Erling Haaland scored both goals after half-time to give Enzo Maresca's side a clean start in the competition.
Aston Villa won 3–2 away to Club Brugge. The English side protected its advantage under second-half pressure, while Pau Torres supplied two assists. It was Villa's first victory of the 2026–27 season.
In France, Real Betis came from behind twice to beat Lille 3–2. Marc Bartra scored twice, Troy Parrott struck the winner and Lille finished with Ethan Mbappé sent off.
Borussia Dortmund defeated Villarreal 3–2, with two late goals from Serhou Guirassy. In Athens, Răzvan Marin's free kick gave AEK a 1–0 victory over LASK.
