ESPN reported the Gunners have officially agreed to a three-year deal with Nketiah who joined Arsenal from London rivals Chelsea back in 2015.
The 17-year-old is coming up through the junior ranks, and was the top scorer in under-18’s competition with 24 goals from 28 games last season.
So far Nketiah has netted three goals inside the opening few weeks of the 2016/17 campaign.
