Arsenal manager Unai Emery was pleased with his side's 3-0 win over Eintracht Frankfurt in the Europa League on Thursday.
Joe Willock's strike gave Arsenal the lead before half-time when his deflected strike left Kevin Trapp helpless.
18-year-old Bukayo Saka was superb throughout the ninety minutes and capped off his performance with a goal and assist, which allowed Pierre-Emerick Aubameyang to score the Gunners third late on.
Speaking after the game, Emery said: "We knew tonight was going to be difficult, they fell back very deep and caused us problems early on.
"We recovered the ball well and the young players showed the confidence to take their chances.
"Everybody can be happy and continuing in this competition is important, so it was good to get a good win, especially away from home."
