Group A
Arsenal 3-0 Ludogorets Razgrad (Nelson 3, Nketiah 81pen 87)
Eddie Nketiah struck twice late on for dominant Arsenal, after Reiss Nelson had set the Gunners on their way with a cushioned effort past Daniel Naumov. However, the hosts would be largely frustrated in their attempts to clinch the points, waiting until the closing stages when Nketiah earned and converted a spot kick before heading in the third.

Paris Saint-Germain 4-1 Basel (Dembele 35, Diaby 47, Giacomini 74, Nkunku 87; Manzambi 76)
Paris overtook Basel at the top of this section with an emphatic victory. Christopher Nkunku impressed for the Parisians by laying on the first two goals, one from a corner, and the midfielder subsequently rounded off the scoring late in the game.

Group B
Dynamo Kyiv 2-1 Benfica (Yanakov 20, Buletsa 57; Mesaque Dju 90+3)
Mesaque Dju's late reply for Benfica was nothing more than a consolation as Dynamo took charge of the section, opening up a three-point lead over their now second-placed opponents.

Napoli 2-2 Beşiktaş (Russo 35, Liguori 85; Alpay Çelebi 28, Muhammed Enes Durmuş 59)
Napoli claimed their first point thanks to a late free-kick by captain Luigi Liguori. Their initial equaliser had also come via a dead-ball situation, Raffaele Russo scoring direct from a corner. Defender Alpay Çelebi, on his competition debut, earlier nodded Beşiktaş in front, and after Russo's reply, Muhammed restored the Black Eagles' lead with a solo effort. 

Group C
Barcelona 1-0 Manchester City (Carles Pérez 86)
The battle of the top two – each with a perfect record before kick-off – was heading for a draw until Carles Pérez profited from the bounce of the ball outside the area and slammed a left-footed shot past Daniel Grimshaw. 

Celtic 1-1 Borussia Mönchengladbach (Johnston 22; Jahn 57)
Both sides picked up their first point in an entertaining encounter in Greenock. Celtic went ahead when Michael Johnston – later sent off for two bookings – turned in Calvin Miller's cross from the right at the second attempt. Mönchengladbach levelled after the break following a superb bulldozing run by Florian Mayer which carried him half the length of the pitch before he teed up Tillmann Jahn.

Group D
Bayern München 0-2 PSV Eindhoven (Abels 28, Lammers 55)
PSV twice punished Bayern for conceding possession inside their own half. Dirk Abels was first to make the German team pay, running onto Sam Lammers' pass and sliding a shot through the legs of Ron-Torben Hofmann. Lammers curled in the second after another giveaway. Bayern's Timothy Tillmann saw red late on for two bookings in as many minutes.

Rostov 1-3 Atlético Madrid (Veber 64; Neskoromny og 45+1, Ballesteros 62, Salomón 83)
Aleksei Neskoromny touched Juan Moreno's cross into his own net in the first half, and Yael Ballesteros's free-kick made it 2-0 to the visitors just after the hour. Blinded by the sun, goalkeeper Carlos Marín blundered to gift Dmitri Veber a swift riposte, but Moreno then sliced open the Rostov defence and fed Salomón to restore the two-goal cushion.
