Borussia Monchengladbach have tabled a cash bid to West Ham for Reece Oxford.
The England U21 international spent last season on-loan at Gladbach, where he impressed, before choosing to stay with the Hammers this term.
However, after a lack of playing chances under manager Manuel Pellegrini, Oxford is now prepared to leave this month.
BILD says Gladbach are eager to re-sign Oxford and have tabled a €12m bid for the youngster.
Gladbach chief Max Eberl wants to bring back Oxford primarily as a centre-half, where they're short of options.
