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.
Nketiah has scored hat-tricks for two different England age-group teams in 2017, for the Under-18s in a 4-0 away win against Qatar in March and the Under-19s in a 7-1 victory over Poland in September.
He has got his chance for Arsenal’s first team this season after scoring 24 goals in the Gunners’ various youth teams in each of the last two seasons.
Current team-mate Alexandre Lacazette has been impressed with the youngster and told arsenal.com: “I really like Eddie, he is very calm in front of goal and has great technique.”
