WHAT HAPPENED
Granit Xhaka was sent off and Pierre-Emerick Aubameyang scored an own goal as we lost our 400th game at Emirates Stadium.
Our Swiss midfielder was a booked after an altercation with Ashley Westwood, but VAR intervened and referee Graham Scott changed the yellow card to a red.
That stopped us in our tracks after a storming start to the second half, and our woes were compounded when Westwood's corner flicked off Aubameyang's head and flew past Bernd Leno.
It was a miserable turn of events after an hour in which we'd created the vast majority of chances.
