A Jesse Lingard double and David de Gea masterclass inspired Manchester United to a 3-1 win at Arsenal, though the victory was soured by Paul Pogba’s second-half red.
Antonio Valencia and Lingard got United off to the perfect start, but Arsenal were back in it early in the second half through Alexandre Lacazette.
Lingard restored United’s two-goal lead before Pogba saw red for a dangerous tackle on Hector Bellerin, which means the France international will miss next Sunday’s derby with Manchester City.
Arsenal failed to break down a resolute 10-man United late on, with De Gea producing 14 saves in total, a joint-record in the Premier League since records began in 2003-04.
The result also sees Arsenal’s perfect home record this season come to an end, while United put the pressure back on leaders City ahead of their match at home to West Ham on Sunday.
United took an early lead through Valencia, who pinched the ball ahead of Sead Kolasinac before playing a one-two with Pogba and drilling the ball through Petr Cech’s legs.
Shkodran Mustafi was at fault for United’s second, with the Arsenal defender dithering on the goal before being intercepted by Lingard, who latched onto Anthony Martial’s delightful flick to steer his effort in off the post.
Arsenal continued to threaten, but Lacazette saw his shot ricochet off De Gea and hit the bar, with Granit Xhaka then skimming the post with the rebound.
A frantic end to the first half saw Bellerin and Kolasinac denied by De Gea, who then produced a stunning stop to prevent Romelu Lukaku from turning the ball into his own net.
Arsenal got one back through Lacazette just four minutes into the second half, with the Frenchman firing home after Aaron Ramsey beat the offside trap to set him up.
Lingard then saw his effort deflect off Cech and hit the post before a sensational De Gea double save prevented both Lacazette and Sanchez from scoring.
United then had their third just after the hour-mark, with Pogba holding off Laurent Koscielny before playing it over for Lingard to tap in.
Pogba’s night was over though just 11 minutes later, with the midfielder leaving his studs in the back of Bellerin’s leg – though Arsenal could not capitalise as United secured their 10th league win of the season.
