The Ukrainian visitor proved stubborn opponents initially, but the result was rarely in doubt from the moment Aubameyang broke the deadlock after 32 minutes.

Danny Welbeck was on target early in the second half before Aubameyang doubled his tally and Mesut Ozil came off the bench to get in on the act.

Captain Vladimir Chesnakov gave Vorskla something to shout about with an excellent finish 14 minutes from time and Vyacheslav Sharpar found the net in similar style with the last kick of the game.

Alex Iwobi was Arsenal's liveliest attacking threat during a largely forgettable opening and the Nigeria international's fine cross allowed Aubameyang to slide home at the back post after Henrikh Mkhitaryan drove at Vorskla on the counter-attack.

Lucas Torriera whipped a free-kick into the side netting before Aubameyang darted inside a pair of challenges to curl an effort against the base of the post.

By the time Vorskla goalkeeper Bogdan Shust pushed a Mkhitaryan attempt over, the away side were certainly in need of half-time.

Upon the restart, Vasyl Sachko's men were unable to stem the tide and Welbeck was on hand to head in Mkhitaryan's 48th-minute centre.

Aubameyang crashed a volley over, but was the beneficiary of Shust's questionable positioning to dispatch Arsenal's third from the edge of the box in the 56th minute – Mkhitaryan again supplying the ammunition.

Stephan Lichtsteiner lifted the ball over the out-rushing Shust for substitute Ozil to grab a fourth in the 74th minute, but the experienced full-back was caught in possession when Chesnakov smashed in an emphatic strike.

Arsenal had long settled for winding the clock down by the time Sharpar sent a side-footed effort flying past Bernd Leno.
