Liverpool also fell behind, but stormed back to beat Burnley 3-1 and cut the gap on leader Manchester City to two points. Tottenham Hotspur climbed to third with a 3-1 win over Southampton while Chelsea hung on to fourth spot, above Arsenal on goal difference, despite a 1-2 defeat at Wolverhampton Wanderers which ended a run of six games without a win.
In the United-Arsenal game, home goalkeeper David de Gea should have comfortably held Shkodran Mustafi’s 26th minute downward header, but merely juggled it over his head and over the line. Anthony Martial levelled six minutes later from close range, with Ander Herrera pulling the ball back after Marcos Rojo’s free-kick was well-saved by Bernd Leno. Arsenal led again in the 68th minute when Alexandre Lacazette got the final touch, but the advantage lasted less than a minute as its defence allowed Jesse Lingard to steal in and slide a shot under Leno. De Gea made crucial late saves to deny Arsenal a first league win at Old Trafford since 2006.
Liverpool responded well as its best start to a top-flight season continued after falling behind at Turf Moor. James Milner equalised for the Reds after Jack Cork’s surprise opener. Substitute Roberto Firmino set Liverpool on course for a 12th win in 15 league games with his first touch before Xherdan Shaqiri rounded things off.
Tottenham Hotspur shook off its north London derby defeat by Arsenal with Harry Kane, Lucas Moura and Son Heung-min all on target for Mauricio Pochettino’s side at Wembley where new Southampton manager Ralph Hasenhuttl watched from the stands. Tottenham has 33 points, six behind Liverpool, and two more than Chelsea and Arsenal.
Chelsea took the lead early through Ruben Loftus-Cheek, but Wolves replied with quick-fire goals from Raul Jimenez and Diogo Jota as Chelsea lost for the second time in three games. Fulham manager Claudio Ranieri welcomed his old club Leicester City to Craven Cottage and shared the spoils in a 1-1 draw while Everton was held 1-1 at home by Newcastle United.
