Viking, who were in Norway's second tier as recently as 2018, scored two first-half goals to take control before England captain Harry Kane equalised with a penalty and back-post header. Luis Diaz gave Bayern the lead with a tap-in but Michael Olise was sent off shortly after for two yellow cards in the same phase of play, including throwing the ball in a Viking player's face. That gave Viking, who are playing in Europe's top competition for the first time since 1992-93, renewed energy. They were the better team after the red card and got a deserved equaliser when substitute Herman Haugen headed home at the back post. Viking, who have two head coaches in Morten Jensen and Bjarte Lunde Aarsheim, are joint top of the Norweigan top flight with Bodo/Glimt, with eight games remaining. They took the lead after 71 seconds when Gianni Stensness rose highest to head home a corner, before Peter Christiansen superbly slot past Jonas Urbig on the break in the 38th minute. Kane's brace, which pulled Bayern level, means he has 36 goals in 40 Champions League games since turning 30, taking him one clear of Messi's record of 35 strikes in his thirties. The 33-year-old has scored in nine successive Champions League games - a feat only achieved by Ruud van Nistelrooy, Robert Lewandowski and Cristiano Ronaldo, who holds the record with 11 games. Bayern host Arsenal on 21 October and will be without Olise after his sending-off, while Viking visit Aston Villa on the same night.

Barcelona sought to extinguish the febrile atmosphere early on by controlling possession, but fell behind after Galatasaray's first proper attack. Seconds after Gordon's claims for a penalty were ignored, Rafael Leao charged down the left wing and cut the ball back into the path of Aleksey Batrakov, who found the bottom corner via a deflection off Joao Cancelo. Galatasaray thought they had doubled their lead six minutes later when Baris Alper Yilmaz diverted Victor Osimhen's header past Joan Garcia, but the goal was disallowed for a marginal offside after a video assistant referee (VAR) check. Barcelona steadied themselves and silenced the frenzied home support two minutes before the break, as Dani Olmo deflected the ball into the path of Joao Cancelo who curled a strike into the corner past Turkish goalkeeper Ugurcan Cakir. Any vulnerability the visitors showed in the first half quickly evaporated in the second as Hansi Flick's side scored twice in quick succession. Fermin Lopez headed in from a Lamine Yamal cross in the 50th minute, and three minutes later a supreme piece of close control from the latter set up Gordon to fire in his first Champions League goal for Barcelona three days after netting for the club for the first time. Fellow summer signing Karim Adeyemi replaced Gordon and arrowed in Barcelona's fourth goal from the left side of the penalty area after Gabriel Jesus touched a Lamine Yamal cross into his path. Barcelona have scored 84 goals in 28 Champions League matches under Flick, giving them the highest goals-per-game ratio (3) in the competition for any club with 20 or more games under a specific manager since 1992-93.

Defender Jurrien Timber sent them on their way in the 64th minute after he collected a pass from Noni Madueke and lifted a clever finish over Berke Ozer. England forward Eberechi Eze added the second three minutes later when he finished first time from substitute Bukayo Saka's cross. Having won at Napoli, Arsenal sealed a second victory in the competition when Saka himself rolled in the third in the 71st minute. Boss Mikel Arteta had made five changes to the side that beat Leeds 2-1 in the Premier League at the weekend, but the frontline of Eze, Madueke and Viktor Gyokeres did not click in a laboured first half from the Gunners. He resisted the temptation to make wholesale changes at the break and was rewarded when Dutch defender Timber found the breakthrough with a neat finish. Saka, Kai Havertz and captain Martin Odegaard were then introduced and all three substitutes played a major role in the next two goals as last season's beaten finalists wrapped up a convincing success. Arsenal won all eight of their league phase games in the previous campaign before they lost the final to Paris St-Germain - and look like they will be hard to beat at this stage of the competition again.

Although head coach Michael Carrick could reflect on a much-improved performance after making five changes to his starting line-up, United have now gone five games without a win. The visitors never recovered after Alex Baena raced beyond Diogo Dalot on to a routine ball over the United defence, before squaring for the excellent Pablo Barrios, whose shot squirmed under Ayden Heaven and into the net. Bryan Mbeumo wasted two good chances to level before the break while Marcus Rashford failed to make contact with Lisandro Martinez's pass. After the interval, skipper Bruno Fernandes came closest when he lifted Youri Tielemans' lofted pass over Atletico keeper Jan Oblak but it dropped off target. The hosts did have chances themselves, with Alejandro Grimaldo clipping a free-kick against the post before Julian Alvarez, making his second start of the season, failed to make the most of an opportunity created by Barrios. United's final hope of an equaliser disappeared when Leny Yoro was sent off for tangling with substitute Jonathan David when the France defender was the last man. Former Everton striker Ademola Lookman sealed the hosts' victory in the 79th minute as United became the first English side to lose in the Champions League this season.

Newcastle goalkeeper Lukas Hornicek hauled down Sidiki Cherif to gift Coventry an early penalty and Jack Rudoni made no mistake with the finish, scoring the club's first goal at home this season to raise the roof at CBS Arena. It was Coventry's first Premier League goal at their home ground since John Hartson scored in a 1-0 win against Sunderland in April 2001. The hosts made a lightning-fast start to the second half, too, and teenager Cherif doubled their lead shortly after the restart with a clean finish. A stunning 70th-minute long-range strike by Sven Botman handed Newcastle a lifeline, but a deflected shot by substitute Ellis Simms put Coventry out of reach - much to the delight of a raucous home crowd. Stephen Mfuni put the cherry on top with four minutes of normal time remaining when he curled past Hornicek into the top-right corner. The victory - Coventry's second of the season - lifts them out the relegation zone and up to 14th, where they sit level on points with Manchester United. Matthias Jaissle's Newcastle remain 11th, with eight points from their opening six games.
