The league phase starts on Tuesday, 8 September 2026, with matches spread across three days. Real Madrid face Inter, Porto host Manchester City, Liverpool meet Atlético de Madrid, and Napoli take on Arsenal in an opening round that already includes several heavyweight games.
This will be the third Champions League season using the 36-team league phase. Every club plays eight different opponents, with four matches at home and four away, before the final league table decides who goes directly into the round of 16 and who must go through the knockout phase play-offs.
In this article, we look at the Champions League 2026/27 fixtures for Matchday 1, highlight the matches worth watching first, and explain what the opening week could tell us about the new campaign. You can also follow upcoming matches, results, standings and odds on our Champions League page.

Champions League 2026/27 at a Glance
There are 36 teams in one league table. Each club plays eight matches against eight different opponents, with four games at home and four away.
The top eight teams in the final league table qualify directly for the round of 16. Teams finishing from ninth to 24th enter the knockout phase play-offs, while teams finishing 25th or lower are eliminated.
That makes every result important. A club is not only trying to qualify. Finishing inside the top eight can also mean avoiding two additional knockout matches later in the season.
Matchday 1 runs across 8, 9 and 10 September, giving fans three straight evenings of Champions League football.

Real Madrid vs Inter
Both clubs arrive with Champions League history and expectations that go far beyond simply reaching the next stage. That makes an opening-night meeting unusually important.
Real Madrid also have a strong recent record in this matchup. UEFA notes that Madrid have won six of the last seven meetings between the two clubs.
There is another storyline on the touchline. José Mourinho now leads Real Madrid against a club with which he has a special Champions League history. Mourinho guided Inter to the trophy in 2010 as part of their famous treble.
For both teams, this is exactly the kind of fixture that demonstrates why the league phase can become interesting immediately. There is no need to wait for the knockout rounds to see two major European clubs facing each other.
Porto vs Manchester City
City will naturally attract attention, but an away game in Porto is not the simplest place to start a Champions League campaign. Porto have a long European history and have lost only one of their last 14 UEFA home matches according to UEFA’s Matchday 1 statistics.
The fixture also marks Manchester City’s 150th European Cup match.
That combination makes this one worth watching beyond the names involved. The first league phase match can quickly become uncomfortable for a favourite if the home side starts well, and Porto have enough European experience to make the evening difficult.
For City, starting with three points would immediately put them in a good position. For Porto, getting a result against one of the competition’s strongest teams would be an excellent way to begin the league phase.
Liverpool vs Atlético de Madrid
Interestingly, the clubs also met at Anfield on Matchday 1 last season, when Liverpool won 3-2. Now they meet again at exactly the same stage.
Liverpool have performed strongly in the league-phase format so far, finishing first in 2024/25 and third in 2025/26.
Atlético, meanwhile, bring the usual experience of Diego Simeone, who remains one of the longest-serving coaches anywhere in top-level European football.
Anfield, Liverpool’s recent league-phase record and Atlético’s ability to make major European matches difficult should make this one of the most interesting fixtures of the opening week.
Napoli vs Arsenal
The clubs have met four times in European competition, with Arsenal winning three of those games. But history is only part of the story here.
Arsenal enter the new campaign after finishing as Champions League runners-up last season. They also produced one of the strongest defensive records in the competition, conceding only seven goals and keeping nine clean sheets.
Starting away in Naples gives them an immediate test.
For Napoli, this is an opportunity to make an early statement at home. For Arsenal, it is a chance to show that last season’s run was not a one-off and that they can again compete near the top of the league phase.
Because every position matters in the 36-team table, even a Matchday 1 result between two strong clubs can become important several months later.
Other Matches to Watch
Borussia Dortmund vs Villarreal is another interesting Tuesday fixture. The teams met in the league phase last season, with Dortmund winning 4-0 at home. Villarreal therefore have an immediate chance to produce a very different result this time.
Barcelona begin at home against Feyenoord on Wednesday. Barcelona have been one of the highest-scoring teams since the league-phase format was introduced, so their opening match will attract attention even if they start as clear favourites.
Sporting CP vs Galatasaray also looks competitive. Both clubs have strong home support, European experience and ambitions to reach the knockout rounds.
Thursday then brings Fenerbahçe vs Roma, a fixture that should create one of the strongest atmospheres of the week.
There are also several clubs that make the 2026/27 competition feel different. LASK enter the Champions League league phase for the first time, while teams such as Sabah and Viking give the opening schedule some less familiar names alongside Europe’s traditional giants.
That mixture is one of the interesting parts of Matchday 1. Real Madrid, Bayern, Barcelona, Liverpool and Manchester City are all there, but they share the week with clubs getting a much rarer opportunity on this stage.
Why the Opening Matches Matter
But the current Champions League format makes position important.
Finishing first and finishing eighth both provide direct qualification for the round of 16. Finish ninth instead, and a club must play an additional two-legged knockout phase play-off.
The difference between those positions can eventually come down to only a few points.
That means a difficult away draw, a late winner or an unexpected defeat in September can still matter when the final table is calculated in January.
There is another reason to follow the opening games closely. Teams do not play every other club in the league. Each team has eight different opponents, so schedules vary significantly.
One club may start against a major European contender, while another begins against a team with much less Champions League experience. Looking only at the table without considering the opponents can therefore be misleading, especially after the first few matchdays.
This is where following fixtures and results together becomes useful. Our Champions League fixtures and standings page lets you keep those different parts of the competition in one place.
Final Thoughts
Real Madrid vs Inter is the obvious headline game on Tuesday. Porto vs Manchester City and Borussia Dortmund vs Villarreal add more interest to the opening night.
Wednesday then brings Liverpool vs Atlético de Madrid and Napoli vs Arsenal, while Barcelona also begin their campaign against Feyenoord.
By Thursday night, all 36 teams will have played once and we will have the first version of the new Champions League table.
Nobody will qualify or be eliminated in September, but the opening week can still tell us plenty. We will see how the favourites start, which home teams can create problems, and which less familiar clubs are ready to compete at this level.
