The West Ham United youngster will spend the second half of the season away on loan in the Bundesliga.
The 20-year-old burst onto the scene with the Hammers in August 2016, when he bossed the game against Arsenal at just 16 years of age.
Oxford has quite literally fallen off the map ever since then, however, making just three Premier League starts, and spending three separate loan spells (now four) away from the London Stadium.
Allowing Oxford to leave has left West Ham rather short at the back, however, with Issa Diop and Angelo Ogbonna the only two fit centre-backs.
Declan Rice can play there, of course, and unless Manuel Pellegrini makes any late signings, there is a real chance that the 20-year-old will have to be utilised in defence.
West Ham fans took to Twitter and reacted in unison to Oxford's departure to Germany...

Loans out center back when that is the position that needs the most reinforcing— Rob2018 (@Westham2018) 31 January 2019
Even if Balbuena gets fit still only leaves 3, how many other prem clubs have 3 senior centre backs??? Oh yeah, us— Dan 父 Good (@DaniGood) 31 January 2019
Not unhappy to see him go wish him luck but best for us and him to part company onwards and upwards ⚒— Mary (@ZaynafamilyMary) 31 January 2019

Better than Ogbonna....— Jamie Norwood (@JimboNorwood) 31 January 2019
Announce our replacement bc ogbonna is pony— Mitchell Cottee (@MitchellCottee) 31 January 2019
Clearly something wrong here he was so good at one point and had so much promise. Has to be worth giving some game time at West ham for rest of season not as if we have a wealth of fit centre backs. If diop gets injured fabianski will need bigger gloves— Staffordshire Martyn (@martynr61) 31 January 2019
