The Champions League league phase got under way with a flurry of results, headlined by Bayern Munich's 5-0 demolition of Bodø/Glimt and Como's impressive 4-1 win over RB Leipzig on their competition debut. Elsewhere, Lens snatched a dramatic 3-2 win at ten-man Slavia Prague with two stoppage-time goals, while PSV came from behind to draw with Shakhtar Donetsk and Roma were held by Fenerbahce, whose manager caused confusion by announcing his resignation only for the club to deny it.

The results in detail:
– Bayern Munich 5-0 Bodø/Glimt: Jamal Musiala, Harry Kane, Alphonso Davies and a Michael Olise brace secured a comfortable win after a goalless first half.
– Como 4-1 RB Leipzig: Martin Baturina, Tasos Douvikas, Assane Diao and Maximo Perrone scored for Cesc Fàbregas's side; Andrija Maksimović replied for Leipzig.
– Slavia Prague 2-3 Lens: Danijel Sturm's second goal put the hosts ahead in the 88th minute, but Florian Thauvin and Ruben Aguilar struck in stoppage time to win it for Lens after Slavia had a man sent off.
– PSV 1-1 Shakhtar Donetsk: Sergiño Dest equalised early in the second half after Gleiker Mendoza's opener, ending PSV's run of five straight opening-match defeats in the competition.
– Roma 1-1 Fenerbahce: Bryan Cristante's opener was cancelled out by Archie Brown, with Fenerbahce's head coach Ismail Kartal briefly announcing his resignation post-match.
