Arsenal looked certain to be the next European giant to fall victim to an improbable comeback until Danny Welbeck came to the rescue.
CSKA Moscow had cut Arsenal’s aggregate lead from three goals to one before late goals from Danny Welbeck and Aaron Ramsey secured passage to the semifinals 6-3 on aggregate after a 2-2 draw on Thursday night.
The hosts gave Arsenal all they could handle early, as Petr Cech spilled a headed shot from Kirill Nababkin into the path of Fedor Chalov, who smashed it into the back of the net to give CSKA a 1-0 advantage at half-time.
Nababkin then doubled CSKA’s lead early in the second half, pouncing on another rebound — this time from a swerving Aleksandr Golovin shot from distance — and volleying home to cut the aggregate deficit to 4-3.
However, Arsenal scored a crucial away goal in the 75th minute, Welbeck curling home a perfect first-time shot after a neat one-two with Mohamed Elneny left him with just Igor Akinfeev to beat.
Ramsey then added a late goal with a lobbed shot in stoppage time to secure a draw on the night for Arsenal.
