The answer to Arsenal's goal-scoring problems was there all along. Mikel Arteta sought to explain the issue this week by pointing to internal data suggesting they carried more of a threat than recent results would suggest, and Saturday's 5-0 win over Crystal Palace highlighted one key aspect: corners.

Arsenal took control of this encounter through two Gabriel Magalhães headers (the second later credited as a Dean Henderson own goal) which underlined the home side's potency from dead-ball situations.

It provided an invaluable route back into some sort of form here, albeit tempered by Palace's passivity -- only Eberechi Eze emerged with any credit from a collectively insipid performance that places manager Roy Hodgson's future under further scrutiny. The irony is, the Gunners didn't even prioritise set pieces during their training trip to Dubai during their midseason break.
