The Athletic has live coverage of the Champions League league phase matches Two hat-tricks, including one that was scored in the space of 12 first-half minutes, tell only part of the story on a night when six Champions League matches delivered 25 goals.For Paris Saint-Germain, who have won back-to-back Champions League titles, it was business as usual. Slovan Bratislava, managed by the former Manchester City midfielder Yaya Toure, were hit for six in the French capital as Ferran Torres, Spain’s World Cup final hero, marked his Champions League debut for PSG with three goals. Ousmane Dembele, with two goals and two assists, didn’t perform too badly either.Marcos Llorente, who enjoys playing (and scoring) against Liverpool so much that he has a dog called Anfield, did it again. The Spaniard put Atletico Madrid ahead inside the first 20 minutes, but goals from Dominik Szoboszlai and Alexis Mac Allister (it pays to be two-footed, kids) turned the game around for Liverpool and gave Andoni Iraola his first Champions League victory.Elsewhere, Barcelona continue to score goals at an astonishing rate, putting five past Feyenoord at Camp Nou, where the miserable weather was the least of the Dutch club’s problems. Raphinha, revelling in his new role as a No 9, scored twice (pity those two Feyenoord players mocked up in a canoe), while Lamine Yamal turned the pitch into a playground for 90 minutes.In Naples, Martin Odegaard — who else? — scored again for Arsenal, taking his tally to four goals in five games this season as the Premier League champions celebrated a 1-0 victory in Italy. Odegaard for the golden boot, anyone?Indeed, Napoli were the only team not to score as Sporting CP beat Galatasaray 3-1, and Stuttgart defeated Viking by the same scoreline, courtesy of Ermedin Demirovic’s blink-and-you’ll-miss-it first-half hat-trick.Matchday 1 results on September 9Barcelona 5-1 Feyenoord
