English born Ghanaian striker Edward Nketiah edged Arsenal past Championship side Norwich City in extra-time to reach the Carabao Cup quarter-finals.

Substitute Nketiah, 18, scored twice after Norwich had taken the lead when James Maddison's pass released Josh Murphy, who dinked a shot past Gunners debutant goalkeeper Matt Macey.

The Canaries, sixth in the second tier, had chances to make it 2-0, but Macey pushed away Nelson Oliveira's curled effort with Murphy and Mario Vrancic also missing chances.

Those misses proved crucial as Nketiah grabbed a late equaliser from close range only 15 seconds after coming on to leave it level after 90 minutes.

The England Under-19 international then headed in from Mohamed Elneny's corner for the winner.

These were Nketiah's first goals for the club in only his second appearance. His first was as an 89th-minute substitute in the 4-2 away Europa League win over Belarusian side BATE Borisov on 28 September.

The Londoner began his career on Chelsea's books but was released at under-14 level in 2015 and joined the Gunners later that year.

The forward has also represented England at Under-18 and Under-19 level and his pace, direct running and heading ability caused a tiring Norwich defence problems at Emirates Stadium.

Manchester clubs City and United progressed with wins over Wolverhampton and Swansea City respectively.
