Arsenal captain Laurent Koscielny admitted his side came close to a Europa League meltdown at CSKA Moscow on Thursday where they recovered from two goals down to snatch a 2-2 draw and reach the semi-finals 6-3 on aggregate.
Having built a 4-1 lead in the first leg in north London last week it seemed Arsenal had plenty of room for error in the CSKA Arena but they were wobbling when Fedor Chalov and Kirill Nababkin scored to give the hosts hope of a memorable fightback.
Danny Welbeck's well-crafted 75th-minute goal and a stoppage time effort from Aaron Ramsey eventually secured a comfortable-looking aggregate victory to keep alive their hopes of qualifying for the Champions League by winning the competition.
