Brentford have asked Barcelona to keep them up-to-date on Andreas Christensen's situation.
With Barça battling LaLiga financial restrictions, Christensen is among the fringe players to be made available this month.
The Independent says Brentford are keen on the former Chelsea defender and hope their Danish connection can convince Christensen about a return to London.
However, for the moment, Christensen wants to stay and fight for his future at Barça.
Along with manager Thomas Frank and his staff, the Bees have four senior Denmark internationals on their books.
Christensen is now inside the final 18 months of his Barça contract.
