What are the key matches to watch as the UEFA Champions League returns?

What the report says

Al Jazeera reports that the UEFA Champions League has returned for its second matchday of the 2026-27 season, with 36 clubs playing across Europe under the competition’s current league-phase format. The article says Paris Saint-Germain sit on top of the standings after the opening round, with Bayern Munich and Barcelona also among the early winners. It notes that this format, introduced in recent seasons, replaces the old group stage with a single league table in which each club plays eight different opponents.

Among the most notable fixtures this week, Al Jazeera highlights Atletico Madrid vs Manchester United and Manchester City vs PSG, along with Arsenal vs Lille, Galatasaray vs Barcelona and Roma vs Real Madrid. The piece says City’s meeting with PSG is especially significant because it comes after a reported finding by an independent commission that City breached more than 100 Premier League financial rules. It also points to United’s difficult start to the season and the prospect of Jose Mourinho facing his former club Roma.

Looking ahead to next week, the article identifies further attention-grabbing matches including PSG vs Barcelona, Liverpool vs Villarreal, Bayern Munich vs Arsenal and Real Madrid vs RB Leipzig. It also flags individual players to watch, including Ferran Torres, Erling Haaland, Michael Olise and Ousmane Dembele, based on their strong starts in the competition. The broader significance is that these early fixtures may shape qualification chances before the knockout rounds begin in 2027.
