Arsenal and Manchester City are tracking teenage West Ham defender Vashon Neufville, sources close to the Hammers have told ESPN FC.
Left-back Neufville, who has represented England at under-16 and U17 level, has yet to make his first-team debut for West Ham but was a substitute for the FA Cup tie against Shrewsbury.
The 18-year-old, on Chelsea's books before joining West Ham as an U14 in 2014, came through the West Ham academy and has been a regular in their U23s this season.
He produced outstanding performances against City and Arsenal last month, bringing him to the attention of both clubs.
Neufville is entering the final year of his contract at West Ham after signing his first professional deal in 2016.
