Giroud’s hat trick send Chelsea to Europa League quarters
Sevilla lost 4-3 at Slavia Prague after conceding a last-minute goal in extra time to go out 6-5 on aggregate, while Eintracht Frankfurt beat Inter 1-0 to advance.
At the Emirates Stadium, Aubameyang celebrated his second goal by pulling on a Black Panther mask he had placed behind the advertising boards, after coming to the rescue for an Arsenal side that lost the first leg 3-1 in France last week.
The Gunners erased that deficit in just 15 minutes, with Aubameyang scoring early and then setting up Ainsley Maitland-Niles for the second, before adding his second in the 72nd.
Marcos Alonso and Callum Hudson-Odoi also had one apiece for Chelsea.
Elsewhere, Napoli advanced 4-3 on aggregate against last year’s semifinalist Salzburg despite losing the second leg 3-1.
Valencia advanced thanks to an injury-time goal from substitute Goncalo Guedes that secured a 1-1 draw at Krasnodar and a 3-2 aggregate victory, while Villarreal eliminated Zenit St. Petersburg 5-2 on aggregate.
