Pierre-Emerick Aubameyang struck twice as Arsenal beat Stade Rennes 3-0 to reach the Europa League quarterfinals and join Chelsea, who earlier on Thursday thrashed Dynamo Kiev 5-0 with a hat-trick from Oliver Giroud.
Arsenal had lost the first leg 3-1 against Rennes in France but it took them just 15 minutes to swing the tie their way.
Their Gabon forward Aubameyang tapped home a cross from Aaron Ramsey with just five minutes on the clock and then turned provider 10 minutes later when he crossed for Ainsley Maitland-Niles to double the lead with a header.
Although Rennes hit the post early in the second period, they were mostly toothless and Aubameyang cemented the victory with another goal from close range after 72 minutes.
Chelsea’s French striker Giroud, the competition’s top scorer this season, got his seventh and eighth goals before Marcos Alonso tapped in a third just before halftime.
Giroud netted his third goal after 59 minutes when he headed home a Willian free kick and Callum Hudson-Odoi added a fifth to cap an 8-0 aggregate victory for the Premier League side.
Inter Milan went out after a 1-0 home loss to Eintracht Frankfurt as Luka Jovic, the 21-year-old striker on loan from Benfica, lobbed goalkeeper Samir Handanovic after six minutes for a lead the visitors never relinquished.
Napoli, Benfica, Slavia Prague and Spanish sides Valencia and Villarreal also booked a spot for the last eight draw.
