Every Champions League Matchday 1 Result: All 18 Scores and What They Mean
Matchday 1 of the 2026/27 Champions League ran across three days and produced two genuine shocks, three emphatic statements, and one result that will be remembered long after the season ends. Here is every score from the opening round, grouped by what actually happened rather than by date.
The Shocks
Two results defied the models by a clear margin. Como 4-1 RB Leipzig is the headline — a club playing its first ever Champions League match beating an established European side by three goals. Lille 2-3 Real Betis saw the Spanish side win away as 29.9% underdogs, the biggest probability upset of the round before Como's result eclipsed it.
The Statements
Three clubs made the most of favourable fixtures. PSG 6-1 Slovan Bratislava starts the three-peat bid with the goal difference PSG have lacked in previous league phases. Bayern Munich 5-0 Bodø/Glimt is a warning to everyone in their group, Manchester United included. Manchester United 4-0 Sabah Masazir marks the emphatic return of a club that missed the competition entirely last season.

The Rest of the Round
Porto 0-2 Manchester City was the quietest important result — City's £197 million rebuilt midfield functioning immediately in a difficult away ground. Borussia Dortmund 3-2 Villarreal produced five goals. Slavia Prague 2-3 Lens gave the French side an away win. AEK Athens 1-0 LASK ended the run of the club that beat Celtic 5-1 in qualifying. Fenerbahce 1-1 Roma and PSV 1-1 Shakhtar were the round's two draws.
What the Round Tells Us Collectively
Post-World Cup seasons reliably produce more variance than probability models expect. Compressed pre-seasons, uneven squad fatigue, and newly assembled squads all introduce noise that historical training data does not capture well. Two clear upsets and several narrower-than-expected wins in a single round is exactly the pattern that history predicts after a summer tournament.
Why Goal Difference Already Matters
All 36 clubs share one table. The top eight advance directly to the Round of 16; ninth to twenty-fourth face a two-legged February playoff with extra fixtures and injury exposure. PSG's +5, Bayern's +5, United's +4 and Como's +3 are not vanity numbers — when clubs finish level on points around the cutoff in January, this is what separates them.
What Comes Next
The league phase now pauses for FIFA's new three-week extended international break, returning on 13-14 October. Matchday 2 brings Atlético Madrid vs Manchester United and Galatasaray vs Barcelona among its fixtures.
