Mathieu Flamini’s 90th-minute own goal denied Arsenal a comeback win over Swansea as Arsene Wenger’s week of misery continued.
After their mauling at Chelsea on Saturday, the hosts started poorly and went behind to Wilfried Bony’s header.
But two goals in 66 seconds changed the mood as Lukas Podolski poked in and Olivier Giroud scored from close range.
The doom returned when the ball ricocheted in off Flamini following Leon Britton’s surge into the box.
It was a calamitous way to concede as Per Mertesacker intercepted the ball but it bounced off goalkeeper Wojciech Szczesny before hitting the French midfielder.
Swansea came away with a point but they were left angry at the end when they were denied a chance to win the game as referee Lee Probert blew up with Jonathan De Guzman bearing down on goal.
