Traditional UEFA Champions League powerhouses Bayern München and Manchester United eased to big victories, with Italian newcomers Como also catching the eye on Thursday and Lens recovering from 2-1 down after 90 minutes to triumph.
The German side hit five second-half goals as they got up and running in impression fashion.
Joshua Kimmich’s effort against the post was the closest either side came in the first 45 minutes, but visiting goalkeeper Nikita Haikin was forced off at the interval and his replacement Julian Faye Lund’s first action was to pick the ball out the net after Jamal Musiala’s strike.
Harry Kane’s header doubled the lead before an unstoppable Alphonso Davies effort and classy late double from Michael Olise rounded off the scoring against a Bodø/Glimt side who ended with ten men following Odin Bjørtuft’s late red card.
Michael Carrick’s men marked their Champions League return with an emphatic win against the competition debutants. Matheus Cunha edged the hosts in front midway through the first half and after Joy-Lance Mickels almost levelled, two well-taken goals in the space of three minutes from Bruno Fernandes and Benjamin Šeško put the Red Devils in control before the interval. Lisandro Martínez rounded off the scoring.
The points were shared in a tight contest featuring two well-executed goals either side of half-time.
Gleiker Mendoza put the visitors ahead with a stunning strike from a tight angle at the end of the first half, but PSV quickly restored parity after the interval when Armando Obispo cut back to Sergiño Dest, who fired in with some aplomb.
Right-back Dest also made a crucial block at the other end to deny Lassina Traoré late on.
Como announced their arrival on European football’s biggest stage with a masterclass in pace and precision. It took Cesc Fàbregas’ side just 15 minutes to open their Champions League account, Martin Baturina slotting in after a neat exchange with Tasos Douvikas, before the roles were reversed 23 minutes later. Assane Diao added a third on the counter after the break, and though Andrija Maksimović pulled one back, substitute Máximo Perrone restored the three-goal cushion in the 90th minute.
