There is something unmistakable about the return of the Champions League. Domestic football can dominate the calendar, but when Europe’s elite clubs gather under the familiar anthem, the stakes feel different. The 2026/27 UEFA Champions League begins its league phase this week, bringing back the biggest names, the biggest nights and the possibility that a club can transform its entire season over 90 minutes.
This is the third Champions League season played under UEFA’s new 36-team league-phase format. Each team plays eight matches against eight different opponents, rather than participating in a traditional four-team group. The league phase runs from September 8, 2026 until January 27, 2027, before the knockout rounds take over. The final will be played at Madrid’s Estadio Metropolitano on June 5, 2027.
A Champions League with unfinished business
The obvious starting point is Paris Saint-Germain. The French champions arrive as holders after an extraordinary 2025/26 campaign in which they successfully defended the trophy, beating Arsenal on penalties after a 1-1 draw in the Budapest final. PSG’s route to the title included emphatic victories over Chelsea and Liverpool before dramatic wins against Bayern Munich and Arsenal.
Their challenge now is different: becoming the team everyone wants to beat.
Defending the Champions League is notoriously difficult, but PSG have already demonstrated that their European project is capable of surviving the pressure of knockout football. They will be expected to go deep again, and watching whether Luis Enrique’s side can maintain that level will be one of the competition’s central stories.
Arsenal also deserve particular attention. Mikel Arteta’s side were beaten only on penalties in last season’s final and had previously become the first club to win all eight of their league-phase matches. They have therefore gone from promising outsiders to genuine European contenders.
Their opening match is a fascinating one: Napoli away on September 9. It is an immediate test of whether Arsenal can turn last season’s breakthrough into sustained Champions League authority.
The giants are coming
Real Madrid remain impossible to ignore. Their history alone makes them one of the teams to watch, but the attraction is also the possibility of another European campaign built around Kylian Mbappé. UEFA notes that the French forward has already established himself among the competition’s elite goalscorers and continues to chase the records of the modern Champions League greats.
Madrid begin against Inter, one of the most attractive fixtures of Matchday 1. It is precisely the kind of game that demonstrates why the new league phase can be exciting: two European heavyweights meeting immediately rather than waiting for a potential knockout tie.
Manchester City are another obvious favourite. Erling Haaland remains one of the competition’s defining forwards, while City’s technical quality and experience make them dangerous regardless of their domestic form. Their first European assignment is Porto away on September 8.
Then there is Barcelona, a club whose young generation has made European football feel exciting again. Their first match is against Feyenoord, but the bigger storyline comes later: Barcelona face Paris Saint-Germain and Manchester City during the league phase. The competition has also produced a particularly intriguing reunion involving Rodri and his former club, City.
Bayern Munich, Liverpool and Atlético Madrid should also be firmly on every shortlist. Bayern have the firepower and European pedigree; Liverpool possess the intensity and experience to trouble anyone; while Atlético remain one of the competition’s most uncomfortable opponents over two legs.
Matches to circle
The first week alone is packed with heavyweight encounters.
Real Madrid against Inter is the standout Tuesday fixture. On Wednesday, Liverpool host Atlético Madrid while Napoli welcome Arsenal. Paris Saint-Germain begin their title defence at home to Slovan Bratislava, while Barcelona host Feyenoord. Bayern then enter the competition against Bodø/Glimt on Thursday.
But the calendar becomes even more compelling.
October brings Bayern versus Arsenal and Paris Saint-Germain versus Barcelona. November offers Atlético Madrid against Bayern, Barcelona against Aston Villa and Fenerbahçe against Liverpool. Arsenal then face Real Madrid in December, potentially providing one of the league phase’s biggest games.
The teams capable of surprising us
One of the pleasures of the Champions League is that it is not simply a parade of superclubs.
Bodø/Glimt are particularly interesting. The Norwegian side have earned their place among Europe’s elite and bring a very different footballing culture to the competition. Viking, another Norwegian representative, are also part of the 36-team field.
Aston Villa deserve attention too. Their recent European rise has turned them into a serious continental competitor, and they open against Club Brugge. Meanwhile, Como’s appearance gives the competition one of its more unusual newcomers, with the Italian club facing RB Leipzig in their opening match.
These teams may not be expected to lift the trophy, but they can make life extremely uncomfortable for favourites.
What we should be happiest to see
The Champions League brings together football cultures that rarely collide in ordinary domestic competition. We get Madrid’s history, Paris’s ambition, Barcelona’s youth, Bayern’s tradition, English intensity, Italian tactical sophistication and the unpredictability of clubs arriving from smaller leagues.
And the new league phase means more meaningful cross-border fixtures from the beginning.
That is what makes the return so exciting. The question is not simply who will win the trophy. It is which young player will announce himself, which giant will stumble, which outsider will become everyone’s favourite and which night will eventually be remembered as the moment the 2026/27 Champions League truly came alive.
Paris begin as champions. Madrid remain Madrid. City have Haaland. Barcelona have ambition. Arsenal have unfinished business.
But history suggests that somewhere between September and June, another story will emerge.
And that is the magic of the Champions League: we know the contenders, but we never know the ending.
