Away surprises on the first day of the Champions League

In addition to Arsenal's triumph at San Mamés , the afternoon began with a 3-1 victory for Union Saint Gilloise at PSV in the Netherlands. The Belgian team, making its debut in Europe's top tournament and one of Atlético's rivals, displayed good football and, above all, a lot of punch.

Juventus and Borussia Dortmund were the two teams that scored the most goals of the night, a 4-4 draw. Eight goals, which also came after the break. Yildiz, Vlaovic (2), and Kelly scored for Juve; Adeyemi, Nimecha, Couto, and Bensebaini did so for the German club.

The other big surprise of the night came from Qarabag, the Azerbaijani team who defeated Benfica (2-3) in Lisbon. A victory that sealed a clear night for the visitors.

Of the half-dozen matches played in the inaugural 2025-26 Champions League, only Tottenham and Real Madrid have collected all three points in front of their home fans.
