Arsenal booked their place in the semi-finals of the Europa League after grinding out a 2-2 draw against a spirited CSKA Moscow at the VEB Arena.
Danny Welbeck's accomplished finish in the 75th-minute and Aaron Ramsey's stoppage-time strike was enough to get the Gunners' over the line and secure a 6-3 aggregate win.
Arsene Wenger's men were overwhelming favourites to go through after beating CSKA 4-1 in the first leg at the Emirates, but strikes from Fedor Chalov and Kirill Nababkin put the Russian side 2-0 up and one goal away from going through.
But Welbeck, who was the hero in the north London side's 3-2 win over Southampton last weekend, came up with a priceless goal that eased the nerves for Arsenal.
