Dieter Hecking has claimed that Reece Oxford wants to "continue playing football" at Borussia Monchengladbach.
However, Gladbach are reportedly interested in recruiting Oxford on a permanent deal, with head coach Hecking appearing to suggest that a bid for the 19-year-old has already been made.
"The ball is now with West Ham and Reece made a clear statement saying he would like to continue playing football in Gladbach and I personally believe that would be the best for his development," Hecking is quoted by Kicker as saying.
"As far as I am informed, there will be another crucial meeting in West Ham today, and then we will have clarity tonight and tomorrow, I will sit down with Max Eberl (Gladbach sporting director) to discuss the situation."
The England Under-20 international, who is also believed to be on the radar of RB Leipzig, signed a new West Ham contract just over a year ago that tied him to the club until 2021.
