It has been reported by the British newspaper that Tottenham, United and City all had the youngster watched on Friday.
The 17-year-old, who can play as central defender or as a defensive midfielder, was in action for the England Under-19 side against their Netherlands counterparts on Friday.
The highly-rated West Ham youngster started the game and helped the England Under-19 side win 2-1.
The victory saw the Young Lions secure their spot in the semi-finals of the Under-19 European Championship and next year’s U20 World Cup.
However, Tottenham, United and City are set to face disappointment if they are planning to make a move for Oxford in the summer transfer window.
That’s because, as reported by The Mirror, West Ham will hold talks over a new deal with the English teenage footballer once he returns from England Under-19 duty.
Oxford featured in seven Premier League games for West Ham last season and could play more matches for the London outfit during the 2016-17 campaign.
