The match, which was largely panned on Twitter for lack of action, took off in the second-half – a string of impressive saves from ex-Gunner Lukasz Fabianski kept his old side at bay.
Bafetimbi Gomis’ header in the 85th minute looked to have been saved by David Ospina, but the referee’s magic watch disagreed and the goal was given.
The Welsh side were able to hold on to their 1-0 lead, and some Gunners fans unbelievably blamed goal line technology for losing the match.
