Arsenal looked be crashing out of the League Cup against lower league opposition on Tuesday before Nketiah rode to the rescue with two goals.
In scoring the first, he made history, becoming the first player born after the appointment of Arsene Wenger to score a goal for the club just 15 seconds after being introduced as a late substitute. Nketiah was born in May 1999, some three years after Wenger's appointment, something which left Wenger stunned post-game. "I must say I am impressed when I think he was not even conceived when I was already here," said the Arsenal boss.

What is his background?
Nketiah was actually with Chelsea for a spell as a youngster, but was released in 2015 for a perceived lack of physicality. Upon his release, Arsenal were quick to offer him a trial and after impressing, the youngster was rewarded with a youth contract.
"I was so down, but then Arsenal found out I was available, contacted my family and invited me to train," Nketiah is quoted as saying after his release from Chelsea.
"Within a week I was told that I would be offered a scholarship. I think it is important to bounce back quickly from disappointment and Arsenal gave me the opportunity to do that."
Speaking after the game on Tuesday, Wenger was at a loss to explain Chelsea's decision to release the player.
"I don't know what happened at Chelsea," Wenger told reporters. "He has scored goals at youth level and sometimes I don't know why they let him go.
"I don't know why. You see that more and more. Young people travel from one club to another. I don't know."
What is his style of play?
As with any quick, young Arsenal striker, Nketiah has already drawn comparisons with 'Gunners' legend Thierry Henry. The 18-year-old is considered to be a speedy, intelligent striker whose movement and desire to get in behind is one of his stand-out traits.
When assessing his own style of play back in March, he explained that: "my game is mainly pace, movement and finishing."
That was backed up by Wenger, who has admitted that: "I like the quality of Eddie's movement, the quality of the areas he gets into, his strength, his determination to finish things off and his work rate as well,"
What is his record like at youth level?
Impressive. Seriously impressive. The youngster plundered 24 goals in 28 games back in 2015/16 to finish as Arsenal U18s' top scorer and once again passed the magic 20-goal mark once again last season, scoring 24 in 33 games in all competitions.
As a youth international he hasn't been doing too badly either, having scored a hat-trick for both England U18s and England U19s in the last 12 months.
What next?
Well, having had his first taste of first-team action he will no doubt be keen to gain more minutes. With Alexis Sanchez, Olivier Giroud and Theo Walcott, amongst others, all being linked with moves away from the Emirates in the near future, there could be a void waiting to be filled if the 18-year-old is up to the task.
It is worth remember though Arsenal fans that for every Henry or Van Persie, there is a Sanchez Watt, Arturo Lupoli or a Quincy Owusus-Abeyie... Which will Nketiah turn out to be?
