Borussia Monchengladbach are still hopeful of keeping hold of Chelsea loanee Andreas Christensen beyond the end of the season.
Christensen, 20, is in the second season of a two-year loan deal with Monchengladbach and has been a regular starter for the club, although he is currently sidelined with a muscle injury.
The Foals have in the past said they are willing to break their transfer record of €15 million to turn the loan into a permanent deal, but now seem to be exploring other options to keep the Denmark international at Borussia Park beyond next summer.
