Arsenal achieved their first away win since November at Premier League strugglers Huddersfield, maintaining their hopes of a top-four Premier League spot as they moved within a point of Manchester United.
United’s 3-0 win at Fulham earlier on Saturday had put them four points clear of the Gunners, who remain sixth – on the same points as fifth-placed Chelsea, who face Manchester City on Sunday (16:00 GMT).
Once Alex Iwobi’s strike deflected into the bottom right corner off defender Terence Kongolo, the visitors rarely looked like relinquishing the points.
Alexandre Lacazette then swept home Ainsley Maitland-Niles’ cross from close range before the interval to seal their win.
While Iwobi and Lacazette missed opportunities to increase Arsenal’s winning margin, Huddersfield also had chances via Adama Diakhaby and Laurent Depoitre.
Saed Kolasinac’s late own goal, though, was a worthy consolation for the hosts, who kept going but have still only managed six goals at home.
The result leaves Huddersfield marooned at the bottom of the table, 13 points from safety with 12 games remaining.
