Arsenal kicked off their Europa League campaign with a healthy 3-0 win away to Eintracht Frankfurt on Thursday night.
Joe Willock, Emerick Aubameyang and Bukayo Saka were on target for the London side, with Saka in particular starring for Unai Emery's side.
The visitors got off the blocks first and should have scored after just five minutes, only for Lucas Torreira to skew his shot way above the post with only the keeper to beat.
Both sides did not fully settle in the opening quarter and had to wait until the 18th minute for a real chance for the hosts.
Filip Kostic met a cross in the box and created some space for a shot, but his effort went wide off the left post.
The Germans came back once again on the 21st minute, Bas Dost finding a good chance from outside the box, picking up a rebound before cutting his marker but rifled his shot high over the bar.
Arsenal seemed to have been stunned in those minutes, and Kostic could have found the net two minutes after Dost's effort, with Damian Matinez managing to keep the ball out.
Arsenal also staged their own attack on the half-hour mark, this time Joseph Willock missing a great chance after finding some space in the box, but his effort went inches wide of the left post.
Three minutes later, Emile Smith latched on to a precise pass and found himself one-on-one with the keeper, but his low shot towards the left side was saved by Kevin Trapp.
Saka then played in Willock, whose deflected shot from inside the box went past the helpless Kevin Trapp to give Arsenal the lead going into the break.
Aubameyang missed a good chance five minutes after the restart, sending the ball wide after a good ball into the box.
Granit Xhaka's long-range effort a minute later went off the crossbar, as they changed the gear in search of a second goal.
Andre Silva received a good ball inside the penalty box on the 59th minute, and immediately fired a first-time effort, which went well over the top.
The home side were reduced to 10 men on the 79th minute, Dominik Kohr receiving a second yellow card for a bad challenge.
Arsenal then took advantage of the numerical strength, doubling their lead with five minutes to go, this time Bukayo Saka's shot from about 20 metres out finding the target.
Three minutes later, Saka turned provider, squaring it to Pierre-Emerick Aubameyang, who beat Kevin Trapp with a brilliant shot into the bottom right corner. 0:3.
The win saw Arsenal ascend to the top of the group.
