Lucas Torreira scored with a bicycle kick in the 82nd minute to earn Arsenal a 1-0 win over Huddersfield Town in a scrappy Premier League game on Saturday.
Torreira leapt to volley home a Pierre-Emerick Aubameyang cross to secure all three points for the Gunners, who had three players booked for diving.
"Our goal is coming later, but it is giving us a deserved result eventually," Arsenal manager Unai Emery told reporters.
The first half was a comedy of errors for Arsenal, with strikers Aubameyang and Alexandre Lacazette missing clear opportunities and midfield lynchpin Granit Xhaka frequently passing the ball straight to the opposition.
Referee Paul Tierney dished out six yellow cards in the half, and nine in the whole match. Arsenal's Xhaka, Shkodran Mustafi and Matteo Guendouzi were all booked for simulation.
Lacazette appeared to break the stalemate just before halftime, latching on to a sloppy backpass and sidestepping keeper Jonas Lossl to slot the ball home, only to be ruled offside.
"He [Torreira] has quality and he is hungry. He can get into the box and score like today," Emery said. "I think today is a very important result."
Arsenal climbed to third in the table ahead of Chelsea and Tottenham Hotspur's matches later on Saturday, while Huddersfield slipped back into the relegation zone, in 18th place.
Huddersfield, who have not beaten Arsenal since 1971, were unable to register a shot on target and manager David Wagner was disappointed not to have held on for the draw.
"If you concede so late in the game, and because of the defensive shift and effort and tactical quality which the players have shown -- how we limited Arsenal, how we kept them away from our goal -- this is enough if you are Huddersfield Town to deserve a point," he said.
"I can see how we performed defensively today against a top-class side and I know we can keep our heads high."
