The England captain scored one of the easiest goals of his career in the 14th minute when he was left unmarked to tap in Konrad Laimer's ball across the face of goal. Neither Lionel Messi nor Cristiano Ronaldo scored their first 20 goals in a season in as few as 12 matches. Kane's strike followed a sensational one by teenage sensation Lennart Karl nine minutes earlier as, aged 17 years and 242 days, he became the youngest player to score for Bayern in the Champions League, surpassing Jamal Musiala's previous record by 121 days. On his first start, Karl fired in a stunning left-foot shot into the top corner after shimmying past two defenders. Luis Diaz smashed in a third off the underside of the crossbar in the 34th minute - his seventh goal since his summer move from Liverpool - before Kane hit the post from a tight angle just before the break. The 32-year-old should have scored again early in the second half, but was thwarted by Brugge goalkeeper Nordin Jackers in a one-on-one opportunity after breaking clear of the defence. Kane was also denied a tap-in by a superb last-ditch block by Jorne Spileers, and replaced by Nicolas Jackson with 20 minutes remaining. The Senegal striker scored Bayern's fourth from close range minutes, sealing a third successive win in the competition, after Diaz had an effort cleared off the line. Bayern moved up to second behind Paris St-Germain in the league phase standings on goals scored with nine points, while Brugge are 20th with three points. The German champions will travel to France on 4 November to face holders PSG (20:00 GMT), while Club Brugge host Barcelona the following day (20:00 GMT).

Scott McTominay opened the scoring and later grabbed a consolation goal for Napoli in an eventful game at Philips Stadion. But seven minutes after the Scotland international's opener, PSV had turned things around with Ismael Saibari's stunning strike putting the Dutch team in front after Alessandro Buongiorno's own goal. Dennis Man added two more for the hosts either side of Lorenzo Lucca's red card, with the Italian striker sent off in the 76th minute for arguing with the referee about a decision against him. McTominay, who enjoyed a stellar first season at Napoli last term, pulled a goal back for the visitors with five minutes of normal time remaining. But his strike was quickly forgotten as Ricardo Pepi restored the three-goal cushion before Couhaib Driouech found the back of the net with a sublime long-range effort to round off a perfect evening for PSV. It is a second straight defeat for Antonio Conte's team, who missed the opportunity to move to the top of Serie A on Saturday after losing to Torino. They drop to 22nd in the 36-team league phase of the Champions League, while PSV jump above the Italians into 11th.

Bellingham has found minutes hard to come by in the Bundesliga since making a £27m move from Sunderland in the summer, but marked his second successive Champions League start by setting up Nmecha's opener. The German forward collected Bellingham's pass in the 20th minute before smashing in a vicious strike from the edge of the penalty area. Copenhagen drew level in comical circumstances - Gregor Kobel did well to keep out a low strike following a corner, but could only watch as Ramy Bensebaini's attempted clearance cannoned off team-mate Waldemar Anton and into the goal. Bensebaini redeemed himself in the 61st minute when he coolly slotted home a penalty after Serhou Guirassy was fouled in the penalty area. Nmecha scored his second of the night when his 76th-minute strike took a deflection and left Copenhagen goalkeeper Dominik Kotarski wrong-footed. Bellingham looked desperate to score his first goal for the club, but it was former Wolves man Fabio Silva who claimed a late fourth. Viktor Dadason's late header creeped over the line for a late Copenhagen consolation. Dortmund will travel to Manchester City on 5 November with seven points after three games, while Copenhagen remain winless after drawing with Bayer Leverkusen and losing 2-0 to Qarabag.

Two smart first-half finishes from Lopez put Barcelona in control, before his third, a Lamine Yamal penalty and a Rashford double halted a short-lived Olympiacos fightback. After playing Yamal through on goal in the seventh minute, Lopez was on hand to finish past the defenders on the goal-line when goalkeeper Konstantinos Tzolakis made a block but could not keep hold of the ball. The Spanish midfielder doubled Barcelona's lead half an hour later when he ran on to Dro Fernandez's ball into space, cut inside and curled a left-footed strike into the left corner. The second half began in bizarre circumstances. Ayoub El Kaabi thought he had halved the deficit with a header, but after checking on the pitchside monitor, referee Urs Schnyder chalked off the goal for offside and instead awarded the visitors a penalty for a handball by Eric Garcia, which El Kaabi converted via the post. Three minutes later Olympiacos midfielder Santiago Hezze was shown a second yellow card and ordered off for catching Lopez with a flailing arm. This was a night when Yamal became the youngest player to reach 25 Champions League appearances – at 18 years and 100 days – and the teenager tucked away a penalty after Rashford was brought down while attempting to round Tzolakis. Barcelona were not finished and were hungry for goals. In the 74th minute Rashford beat Tzolakis with a well-placed low finish, and then two minutes later Lopez smashed in his third from the edge of the box to become the first Spaniard to score a Champions League hat-trick for the Catalan side. Rashford drilled his second after controlling a cross-field pass with a delightful touch. In 37 Champions League games for Manchester United, he scored more than one goal on just one occasion, but it has happened twice already with Barcelona. This was the first time since they famously beat Paris St-Germain 6-1 in 2017 that Barcelona have scored six goals in a Champions League match. Barcelona have six points after three games of this campaign after beating Newcastle 2-1 and losing to PSG by the same scoreline. Olympiacos remain on one point, and have now lost each of their last 12 Champions League away games.

The Gunners started the game quickly and Eberechi Eze's deflected shot hit the bar in the first half, while Atletico's Julian Alvarez nearly caught out David Raya with a long-range effort while the goalkeeper was stranded outside his area. The rest of the first half was cagey and that carried on into the second 45 minutes initially, with supporters wondering where the opening would come from. Centre-back Gabriel Magalhaes answered that question when he headed in Declan Rice's excellent free-kick in the 57th minute. That started a devastating spell for Arsenal as the home side made their usually solid opponents suffer. Gabriel Martinelli scored with a curled shot after a driving run from Myles Lewis-Skelly, before striker Viktor Gyokeres bundled in his first Arsenal goal for eight matches. The Sweden international then got his second of the night three minutes later when he converted Gabriel's knockdown from another dangerous Arsenal corner. The result means Arsenal have won their opening three games of the competition and have still yet to concede a goal.
