The 18-year-old defender has sealed a season-long loan switch to the German club, hoping to gain first team experience in the Bundesliga
Borussia Monchengladbach have signed England Under-20 defender Reece Oxford on loan from West Ham.
The 18-year-old joins the Bundesliga side until the end of the 2017-18 season, having spent the second half of last season on loan at Championship club Reading.
Oxford broke into the Hammers first team during the 2015-16 season, having made his competitive debut as a 16-year-old in the Europa League qualifying stages. He became West Ham's youngest ever player, and then went on to become the second youngest Premier League starter.
