Goals from academy gradates Joe Willock and Bukayo Saka helped Arsenal overcome a difficult test against Eintracht Frankfurt and begin their Europa League campaign with a victory.
Willock put the Gunners in front with a deflected shot in the first half before Saka smashed in his first senior goal for the club in the 85th minute.
Pierre-Emerick Aubameyang added a third two minutes later as Arsenal ended their three-game winless run.
The Gunners had created further chances but also relied on goalkeeper Emiliano Martinez to come to the aid of their fragile defence.
After Dominik Kohr was sent off, Bukayo Saka cut loose with a goal and an assist to lead Arsenal to a 3-0 win over Eintracht Frankfurt.
Bukayo Saka put 10-man Eintracht Frankfurt to the sword as Arsenal began their Europa League campaign with a 3-0 victory at the Commerzbank-Arena.
Making his second start for Arsenal, 18-year-old Saka opened his account for the club in the 85th minute and added an assist for Pierre-Emerick Aubameyang two minutes later as a much-changed line-up bounced back from a second-half collapse against Watford in the Premier League on Saturday.
The late flurry came after Dominik Kohr was shown a second yellow card for a trip on Saka, with Joe Willock having opened the scoring, after another Saka assist, in an open encounter in Germany.
