Eddie Nketiah scored his first Premier League hat-trick as Arsenal disposed of bottom club Sheffield United.
A crisp turn-and-finish in the first half set the Gunners on their way before the England striker buried a poacher's finish after the break and capped a memorable day with a stunning rocket from 25 yards. Fabio Vieira and Takehiro Tomiyasu then rounded off the scoring late on in another dismal display for the Blades.
