Hansi Flick's side broke the deadlock after just five minutes when Lamine Yamal ran in behind the Valencia defence and converted a perfectly weighted through ball from Fermin Lopez. Lopez doubled the lead when he rifled Anthony Gordon's lay-off into the bottom left corner of Stole Dimitrievski's goal. It was Lopez's fourth goal and Gordon's fourth assist in as many matches this season. Barcelona began the second half as ferociously as the first when Raphinha tapped in his sixth goal of the season. Lopez, Barcelona's best player on the afternoon, sprinted the length of the attacking half to set up the former Leeds winger for his 50th goal in the Spanish top flight. Midfielder Pedri combined with Dani Olmo for a one-two and neatly slotted home to score Barca's fourth, before Olmo slithered between Valencia midfielders to slip Lamine Yamal through for his fourth goal of the campaign.

Chelsea stunned the home fans by taking a second-minute lead through £117m summer signing Morgan Rogers' volley after the Gunners failed to clear Reece James' free-kick. That was the first goal Mikel Arteta's side have conceded this season. Despite their flying start, Chelsea had not kept a clean sheet in their previous 18 Premier League games and Xabi Alonso's side were forced to withstand wave after wave of Arsenal pressure. Emiliano Martinez denied Bukayo Saka, while Jorrel Hato and Wesley Fofana each made crucial blocks before the Gunners levelled in the 25th-minute after former Chelsea forward Kai Havertz beat Martinez at his near post with a well-placed finish. In a high-quality match, Chelsea - who spent close to £350m in the summer transfer window - came within a whisker of retaking the lead. After captain James had forced David Raya into a save from outside the box, Pedro Neto hit the post after a wonderful solo run before Martin Odegaard settled it in the 50th minute. The Arsenal captain beat Martinez after Havertz's clever dummy, the Norwegian's second goal in three Premier League games. Chelsea substitute Estevao thought he had equalised right at the end of the game but Raya produced a brilliant finger-tip save as the Blues lost for the fifth straight league game at Emirates Stadium.

The former Arsenal full-back, who joined Everton from Lyon on transfer deadline day, left United goalkeeper Senne Lammens rooted to the spot when he curled an unstoppable effort into the net to deny the visitors a first away win of the season. Michael Carrick's side looked set to seal all three points at Hill Dickinson Stadium for the second consecutive season after Bryan Mbeumo and Benjamin Sesko scored either side of Tyrique George firing Everton level. But Maitland-Niles' first Premier League strike since December 2019 maintained Everton's unbeaten start to the season at the end of a turbulent week on Merseyside. Fresh from hitting Ipswich Town for five last weekend, United made a fast start and almost went ahead inside eight minutes when Bruno Fernandes struck the crossbar following a knockdown from Mbeumo inside the area. It was the 24th time United had hit the woodwork since the start of last season, more than any other Premier League side. But that did little to dampen United's mood as they, and Marcus Rashford in particular, continued to ask questions of the Everton defence. Only days after selling the creative Iliman N'Diaye to Manchester City in a deal worth up to £65m, Everton showed little ingenuity or originality in the final third. That was until two minutes before half-time when Thierno Barry, the club's top scorer this season, headed over after a wonderful cross from makeshift full-back Merlin Rohl, and Jarrad Branthwaite forced a save from Lammens. But the United breakthrough came less than 60 seconds into the second half, with Mbeumo picking the ball up from Kobbie Mainoo before curling a spectacular effort past Jordan Pickford to double his tally for the campaign. Brennan Johnson almost drew Everton level, while Rashford continued to threaten. Everton manager David Moyes summoned summer signings Jack Grealish and Hayden Hackney from the bench midway through the second half, and Hackney was involved in the equaliser when he teed up George to rifle home at the near post. United thought they had won it when substitute Sesko made it two goals in as many visits to Everton by heading home Luke Shaw's cross. But it was an Everton substitute who had the final say, with Maitland-Niles' strike sending the home fans into raptures.

Manchester City highlighted their early season credentials by maintaining their 100% winning record after three Premier League games, but had to cling on to leave newly promoted Coventry still searching for their first point of the campaign. The result was ultimately a satisfying one for City manager Enzo Maresca after giving debuts to Iliman Ndiaye and £125m signing Enzo Fernandez, with the Argentine drafted in minutes before kick-off after Nico O'Reilly sustained an injury in the warm-up. City's star striker Erling Haaland was the match-winner, powerfully heading home the only goal of the afternoon after Antoine Semenyo dug out a cross to the far post. Fernandez played a key part in the goal with a slide-rule pass to the Ghanaian. On another day, Norway striker Haaland could have had a hat-trick. He had a thumping effort pushed away by visiting goalkeeper Carl Rushworth and another close-range strike in the second half ruled out for offside. Rayan Cherki turned inside and struck against the foot of a post after being set up by Fernandez, but City were thankful to goalkeeper Gianluigi Donnarumma, who made a string of saves. The Italy captain kept out Jack Rudoni's diving header at the far post and Loum Tchaouna's low strike with a full-length save, and stood tall to deny substitute Ellis Simms late on. Frank Lampard's men should have gone ahead when Taiwo Awoniyi picked up a loose pass from Semenyo and ran through on goal, but the Nigerian struck wide to leave Coventry without a goal this season.

Luis Diaz came closest to putting Bayern in front when he spurned one-on-one chances either side of half-time. First, he shanked a shot wide with only Loris Karius to beat, before he saw a tame chip over the goalkeeper cleared well before it reached the goalline. After opening the season with a thumping 5-1 win against VfB Stuttgart and a 4-1 victory over second-tier side Osnabruck in the DFB Pokal, Bayern manager Vincent Kompany opted to rotate his side. Harry Kane and Michael Olise watched from the bench as Bayern dominated possession, but did little with it in a disjointed first-half performance. England captain Kane come on at the break, but it was not until the introductions of Olise and Jamal Musiala with 35 minutes remaining that Bayern began to ramp up the pressure. Musiala was included in the squad for first time this season after suffering seizures during two pre-season matches. Bayern's Konrad Laimer sliced into the side netting from close range, before Kane forced Karius into a stunning fingertip save with a late drive destined for the top corner. Bayern could not penetrate a compact and disciplined defence as Schalke held on to collect their first point of the season. This was Kane's 96th Bundesliga appearance, and he needs two more goals to reach 100 in the competition. The record for the fewest matches to reach a century is 129. Kane began the day having scored against all 20 teams he had faced in the Bundesliga, and has now netted against 20 out of 21. It is the first time in 67 Bundesliga matchdays - almost two years - that Bayern will not finish on top of the table. Bayern host Bodo/Glimt in their opening Champions League game on Thursday before travelling to Bundesliga newcomers Elversberg on 13 September.
