Arsenal put up an attacking show, as Arsene Wenger took charge of his final game at the Emirates Stadium on Sunday.
The Frenchman will be standing down from his post after 22 years in charge.
Pierre-Emerick Aubameyang opened the floodgates in the 14th minute, sliding in Alexandre Lacazette’s cross-shot. Lacazette himself doubled the lead shortly before half time, finishing off Hector Bellerin’s cross.
Sead Kolasinac thumped in a third after the break, before Alex Iwobi fired into the roof of the net following great work from Aubameyang.
Aubameyang then tucked away Bellerin’s cross, to seal an emphatic win.
