Borussia Monchengladbach have announced the signing of West Ham defender Reece Oxford on a one-year loan deal.
Oxford, 18, spent the second half of last season on loan at Reading but made only five appearances as they reached the Championship playoff final.
Announcing his arrival, Gladbach said: "Borussia Monchengladbach have agreed a loan deal with West Ham United for Reece Oxford. The 18-year-old defender will join the Fohlenelf on a contract running until June 2018."
Gladbach sporting director Max Eberl added: "Reece Oxford has played for England at youth level and is considered one of the country's best young defensive talents. This loan deal gives us the chance to add a very interesting player to our squad. On top of that, we've had good experience with signing young Premier League players in the recent past."
Oxford, who made his senior debut at the age of 16, remains under contract at West Ham until 2021 and has so far appeared in seven Premier League matches and two Europa League qualifiers for the Londoners.
West Ham boss Slaven Bilic said: "This is a fantastic opportunity for Reece to continue his development and experience top-level European football on a regular basis. He will play in a league which is very technical, which can only help him immensely, and he will also learn a new culture and gain valuable life experience.
"We believe Reece has a very exciting and successful future here at West Ham, and he now needs regular first-team football to ensure his progress continues. We wish Reece all the very best in this adventure, and look forward to welcoming him back to the club at the end of the season."
He becomes Gladbach's fifth signing of the summer, but the only one with Bundesliga experience is Vincenzo Grifo, 24, who joined from Freiburg.
Dieter Hecking's team have lost Germany under-21 international Mo Dahoud to Borussia Dortmund and defender Andreas Christensen, 21, who has returned to Chelsea following a two-year loan.
But they hope they can lure Christensen away from Stamford Bridge should he fail to win a squad place during Chelsea's preseason.
