AC Milan survived a grilling at Arsenal to reach the Champions League quarter-finals 4-3 on aggregate, despite losing the second leg of their last 16 tie 3-nil in north London.
After seemingly wrapping up the tie in the San Siro last month with a 4-nil victory, Milan's advantage all but evaporated before halftime as goals by Laurent Koscielny, Tomas Rosicky and Robin van Persie threatened one of the competition's greatest comebacks.
Van Persie missed a great chance after the break to level up the tie as the home crowd roared their side forward, although Milan were also guilty of wasting several gilt-edged chances to calm their nerves on a fraught night.
Benfica also progressed after beating Zenit St Petersburg 4-3 on aggregate.
