Reece Oxford is to return from his loan spell with German Bundesliga side Borussia Monchengladbach, manager David Moyes confirmed in his Friday press conference.
Oxford spent the first half of the season in Germany, featuring in three top flight and one German Cup matches during his loan spell.
The 19-year-old became the Hammers' youngest-ever player when he made his debut aged just 16 in a UEFA Europa League tie against Andorran side Lusitans in July 2015.
He has gone on to make 14 senior appearances to date in Claret and Blue and Moyes is looking forward to working with the England U20 international.
"Reece Oxford will come back. We will take a look at him and see how he is," the manager confirmed.
"I hope we can help improve him - I've only just met him, but I know he is well thought of here and we will work with him."
