Swansea City came from behind to beat Arsenal at the Emirates Stadium and move six points clear of the relegation zone.
The hosts started much the brighter and after several near misses, they took the lead when Joel Campbell thundered home from an angle.
But Swansea hit back before the break as Wayne Routledge beat Petr Cech with a cool finish after being played through by Jack Cork, and they completed the dramatic turnaround with 15 minutes left as Ashley Williams turned home a Gylfi Sigurdsson cross to send the 2,000 travelling fans into raptures.
Arsenal tried to respond late on but the Swans defence held firm to hold on for a crucial three points ahead of a set of important fixtures in the coming weeks.
Victory moved the Swans onto 30 points - six clear of third-bottom Norwich City.
The Emirates Stadium has been a happy hunting ground for Swansea since they won promotion, but it was a tough opening quarter for the visitors on this occasion as Arsenal created three decent openings within the first ten minutes.
First it was Olivier Giroud who had a sight of goal before he saw a low shot blocked by Williams, and the Swans skipper was called into action soon after as he blocked from the same player after a cut back from Hector Bellerin on the right.
But the Gunners’ best chance fell to Alexis Sanchez in the 10th minute as Campbell’s chipped pass was flicked on by Mesut Ozil and after Sanchez jinked past his marker he was unfortunate to see a curling shot come back off the foot of the post.
However, Sanchez played a key role just five minutes later as the home side were rewarded for their dominance by breaking the deadlock.
After patient build-up outside the penalty area, Sanchez picked up the ball on the left edge of the box and he clipped a fine pass into the box for Campbell who produced a lovely left-foot finish on the turn that gave Lukasz Fabianski no chance in the Swansea goal.
The former Arsenal stopper also saved well from Bellerin’s 25-yard drive, while the visitors’ best chance of the opening half an hour came from Leroy Fer as the on-loan midfielder saw a 20-yard effort just evade the crossbar.
That marked a good period of play for Swansea who were seeing more of the ball, and the visitors stunned the Emirates crowd with an equaliser on 33 minutes as Cork played a fine pass through for Routledge who coolly slotted past Cech for his first away goal since January 2012.
That setback sparked Arsenal back into life and the hosts finished the half strongly as Giroud saw a fierce right-foot volley cannon back off the crossbar on the stroke of half-time.
The Swans made a change at the break as Sigurdsson was introduced in place of Ki Sung-Yueng.
And it was the visitors who created a couple of openings, with Stephen Kingsley sending in a fine low cross that evaded everyone in the six-yard box, while Andre Ayew drifted in from the right flank before shooting wide of goal.
At the other end, Sanchez shot wide of the left-hand post as the Gunners looked to wrestle back the initiative.
The hosts then made their first change of the evening as goalscorer Campbell was replaced by Danny Welbeck with a quarter of the game remaining, while youngster Jay Fulton was introduced in place of Fer for Swansea.
But it was Arsenal who came mightily close to retaking the lead as Sanchez saw a 20-yard free-kick come back off the upright with Fabianski beaten.
However, the contest took a dramatic twist with 15 minutes left to play as the Swans took the lead.
After Ayew was fouled on the right flank, Sigurdsson whipped in a fantastic free-kick that was turned home by captain Williams from six yards out.
Giroud saw a header comfortably saved by Fabianski as Arsenal looked to get back on level terms, but the Swansea defence held firm throughout the closing stages.
And the visitors worked tirelessly for the final moments as the whistle went to cap a memorable night in North London.
