Brentford have made a move for Crystal Palace defender Joachim Andersen.
The Athletic reports the Bees have attempted to open talks with Palace over a 20m deal for the Dane.
However, Palace are insisting Andersen isn't for sale.
Andersen is also a target for Newcastle United and Palace have let it be known it will take much more than 20m to bring them to the table.
The Bees are also in talks with Wolves over their centre-half Nathan Collins.
