First-half goals from John McGinn, Emi Buendia and Nicolas Jackson earned the Premier League side a battling victory in Belgium. Hugo Vetlesen had briefly hauled the hosts level after McGinn's opener, but Buendia and Jackson - with his first goal for the club - put Villa in charge. Nicolo Tresoldi's 61st-minute penalty after Aaron Wan-Bissaka's handball left the visitors facing a nervy last 29 minutes during which Tresoldi hit the post. But Villa held on for a result they will hope to use as a platform to build from after three successive league matches without scoring, as manager Unai Emery looks to integrate 10 new signings. The Europa League winners have lost six of the starting XI from their triumphant night in Turkey, including £117m Morgan Rogers after his exit to Chelsea. Emery has called for patience, knowing it will take time to rebuild. And it was skipper McGinn - their longest-serving player - who energised their season, becoming Villa's record European scorer in the process with his 12th goal.

The former Tottenham man continued his strong run of form since joining Betis last month, having also scored the only goal in victory against Real Madrid on Friday. Lille dominated the first half, but a strong performance after the restart - and a Lille red card - helped the Spaniards to victory. Ayase Ueda, a summer arrival from Feyenoord, got his second goal in as many games when he nodded in from close range after a well-weighted delivery from Ethan Mbappe, the brother of Real Madrid star Kylian. Lille began to assert dominance but Betis soon restored parity when Marc Bartra met a whipped Pablo Fornals cross and sent a diving header past Berke Ozer. Both sides scored with their first efforts on target and Lille got back in front with their second when Alexsandro nodded in an outswinging Gaetan Perrin corner. But Bartra levelled once again just three minutes after the restart when his slight headed touch directed an Isco free-kick past Ozer. The Spanish side then got what would turn out to be the winning goal when Parrott rifled a low effort into the far corner. Lille's night then rapidly worsened with Mbappe shown a red card after appearing to elbow Natan off the ball. The French club pushed for an equaliser, bringing on attacking reinforcements including former Arsenal and Chelsea striker Olivier Giroud, but were unable to breach the Betis defence. Lille travel to Arsenal for their next Champions League game on 13 October (20:00 BST), while Betis host Porto on 14 October at 20:00 BST.

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.
