Liverpool, Arsenal, Chelsea and Tottenham are tracking Stevenage's teenage defender Ben Wilmot, sources close to the League Two club have told ESPN FC.
The four Premier League clubs all watched Wilmot in action during last weekend's FA Cup clash with Reading.
Wilmot played the full 90 minutes and impressed as he helped Stevenage earn a goalless draw.
The 18-year-old has come through Stevenage's academy and signed his professional contract at the club last April.
He has yet to make his debut in League Two for Stevenage, but he has made four appearances in all competitions so far this season.
Liverpool, Tottenham, Arsenal and Chelsea have all been making regular checks on Wilmot this season as they weigh up moves.
Brighton & Hove Albion are also interested in Wilmot and have seen a couple of bids rejected.
Stevenage have high hopes for Wilmot and they are bracing themselves for offers for their prize asset before the close of the transfer window.
