IArsenal roared back from 2-0 down to draw against Chelsea last week to preserve their unbeaten league record.

Boss Mikel Arteta shuffled his pack --including dropping captain Martin Odegaard to the bench -- for the visit of Sheffield United and Nketiah celebrated his recall in style.

Arsenal broke through a resolute Blades defence as Declan Rice's pinpoint pass was collected by Nketiah, who made no mistake with a close-range finish past Wes Foderingham.

Nketiah doubled up when Foderingham failed to deal with a Bukayo Saka corner and palmed the ball into the path of the England striker, who lashed home to make it 2-0.

Nketiah's hat-trick was sealed in style as he smashed home from 20 yards.

Arsenal were awarded a penalty after a lengthy VAR check for an Oliver Norwood foul on Fabio Vieira, the Portuguese midfielder taking the spot-kick himself and sending Foderingham the wrong way to make it 4-0.

Another substitute, Takehiro Tomiyasu, completed the rout in stoppage time.

The win lifts Arsenal two points behind pacesetters Tottenham, who beat Crystal Palace 2-1 on Friday.
