The Gunners conceded three late goals to gift Anderlecht a point in the Champions League on Tuesday and Arsene Wenger's men capitulated in the English Premier League on Sunday as Swansea came from behind to claim a 2-1 victory.
Alexis Sanchez had put Arsenal ahead with his 12th goal of the season, but Gylfi Sigurdsson scored a curling free-kick and substitute Bafetimbi Gomis headed home Jefferson Montero's cross with his first touch to give the Swans the win.
The result means Swansea leapfrog Arsenal into fifth position, level on points with fourth-place West Ham.
