#2 Hit: Hector Bellerín

A wing-back? An unorthodox winger? It's becoming clearer with each passing week that although criticism of Hector Bellerín defensively is warranted, his attacking capabilities are impressive and he utilised them to great effect here.
He set up Aubameyang for Arsenal's fourth, a deft flick proved instrumental during the build-up to Ramsey's backheel finish and he could've had a goal of his own - having forced Bettinelli into a diving stop from range.
He completed two tackles, two interceptions and blocked a shot too, in a busy afternoon for the Spaniard. Naturally, there's still room for improvement as his decision-making can often prove baffling and deliveries into the dangerous areas are inconsistent - but this type of performance will provide him some much-needed confidence with matches coming thick-and-fast.
