Arsenal earned a first away win in the Premier League since November, beating Huddersfield Town 2-1 at John Smith's Stadium.
Alex Iwobi's 16th-minute deflected volley gave Arsenal the lead before Henrikh Mkhitaryan was denied by Ben Hamer.
Alexandre Lacazette doubled Arsenal's lead a minute before the break, converting Ainsley Maitland-Niles' cross from close range.
Huddersfield Town's Adama Diakhaby forced a smart save from Bernd Leno shortly after the break before curling another effort wide.
The home side did claim just a sixth home goal this season when Karlan Grant scored from close range in the third minute of stoppage time.
Arsenal stay sixth on 50 points, while Huddersfield remain bottom on 11 points, 13 off safety.
