Lucas Torreira's late winner saw Arsenal beat Huddersfield Town 1-0 in the Premier League at the Emirates Stadium on Saturday.
The Gunners dominated the first half but were frustrated against a resolute visiting side. Strikers Pierre-Emerick Aubameyang and Alexandre Lacazette both wasted fine chances, and the Frenchman also had an effort ruled out for offside.
Torreira also came close to breaking the deadlock just before half-time. The Uruguayan's fierce shot from range looked to be heading for the top corner until a diving Jonas Lossl managed to tip it around the post.
Unai Emery made a double change at the break, sending on Alex Iwobi and Henrikh Mkhitaryan but still Arsenal toiled against the Terriers.
