Despite still being two months short of his 19th birthday, Nketiah has already made eight appearances for the first team at the Emirates Stadium, with two goals coming on his second outing against Norwich City in the EFL Cup earlier this season.
Nketiah is still to make his first start for Arsenal, but the teenager says that he is only benefiting from being able to train alongside both Lacazette and Aubameyang.
The youngster is quoted by Football.london as saying: "I've been watching their movement, how they finish in front of goal. Everyone has a different style, so I'm just trying to pick up a few things from them.
"They're world-class strikers, so to be able to train with them and learn from them is a great feeling. I just want to keep working hard by learning from the best."
Nketiah has featured for a total of 126 minutes since making his debut at the end of September.
