Abuja-Arsenal suffered another painful English Premier League defeat on Tuesday as Swansea City capitalised on some glaring errors to win 3-1 at the Liberty Stadium.
The result boosted the Welsh side’s survival hopes and dented the visitors’ top four chances.
Arsenal took the lead through Nacho Monreal after 33 minutes, but their advantage lasted just seconds as Mesut Ozil gave the ball away and Sam Clucas finished for the home side.
Worse was to come for Arsenal in the second half as goalkeeper Petr Cech sliced an attempted clearance, leaving Jordan Ayew to fire home after 61 minutes.
Clucas finished with a right foot effort to grab his second of the night with four minutes remaining.
The defeat leaves Arsenal in sixth place, eight points adrift of Liverpool in fourth, while Swansea, who have been rejuvenated by new manager Carlos Carvalhal, climbed out of the bottom three.
They moved above Stoke City on goal difference.
