Monaco also wins away at Bodo/Glimt and Tottenham wins at home against Copenhagen. Olympiacos and PSV draw 1-1

Arsenal make it four out of four. Arteta’s team thrash Slavia Prague 3-0 and remain top of the Champions League with 12 points. The Gunners continue to fly: it is their tenth consecutive victory in all competitions, the eighth without conceding a goal. With Gyokeres out due to injury, Merino took it upon himself to lead the team: the former Real Sociedad player scored his first brace of the season. Saka broke the deadlock with a penalty. In the second half, Dowman, born in 2009, came on as a substitute for Trossard. At 15 years and 308 days, he is the youngest player to make his debut in the history of the competition. Bayern Munich responded to Arsenal by beating European champions PSG 2-1. Luis Diaz was the protagonist, albeit in a negative way: the Colombian striker scored twice, then got himself sent off for a harsh tackle on Hakimi. The former Inter player was forced to leave the field in tears. Luis Enrique’s men’s reaction came too late: Joao Neves’ goal in the 74th minute was not enough. Kompany’s team caught up with the Gunners at the top and even won their 16th consecutive victory. First defeat in the Champions League for the French.
Xabi Alonso’s return to Anfield was a bitter one. Real Madrid fail to beat Liverpool, Courtois tries to save his team but a header from Mac Allister condemns the Galacticos. The Reds win again and forget their crisis. The same goes for Atletico Madrid, who beat Union Saint-Gilloise 3-1 and get back on track after their heavy defeat in the third round against Arsenal. Alvarez, Gallagher, and Llorente score. Inter is warned. Tottenham runs riot against Copenhagen: it ends 4-0, despite the Spurs being a man down after Johnson’s red card in the second half. Monaco wins against Bodo/Glimt, Juventus’ next opponent. Olympiacos were denied in the 93rd minute by PSV Eindhoven: it ended 1-1.
