The 16-year-old defender has featured during the Hammers’ pre-season programme and has already made his competitive debut for the London outfit.
The centre-back played for Slaven Bilic’s side during the first leg of their Europa League first qualifying round against FC Lusitans last month.
Oxford played well against the Andorran side and was impressive during the 3-0 win at the Boleyn Ground.
The England Under-18 international captain normally plays as a centre-back, but on that occasion he was deployed in midfield.
Oxford became the youngster ever player to play for West Ham, breaking Billy Williams' 93-year record in the process.
The youngster is likely to get chances in the first team this season, but Dicks has urged caution despite hailing him as a “top talent”.
@JULIAN3DICKS do you expect Reece Oxford to feature regularly in the prem?— George Priestley (@GPriestley1) August 3, 2015
He's still only 17, so he has to be looked after game wise. But a top talent https://t.co/AhVAyETjBq— Julian Dicks (@JULIAN3DICKS) August 3, 2015
West Ham have a good and competitive squad, but there will be times when Oxford will be needed.
The youngster could be given valuable first-team experience in cup games, although at this stage of his career, he should be more focused on doing well with the West Ham youth teams.
