Arsenal in disarray as CSKA Moscow score twice to set up unlikely Europa League comeback

Arsenal went into the second leg with a 4-1 lead after a rout at the Emirates, but - on a remarkable week of upsets - CSKA have moved within touching distance of a famous result.

Here's how the drama unfolded:

Is the comeback on? Fedor Chalov breaks the deadlock and CSKA Moscow are ahead on the night. Kuchaev delivers a great cross, Monreal is beaten in the air by Nababkin whose header is parried by Cech into the path of Chalov and he is perfectly positioned to tap the ball into the net.

Now it really is game on! Cech should do better with Golovin's shot from 30 yards. He can only parry it into the feet of Nababkin who finishes from an acute angle. Monreal doesn't react quick enough. CSKA Moscow only need one more goal!
