The West London club have explored the player’s situation and Dortmund have been informed of their interest.
However, the Bees are not alone in their pursuit of the 22-year-old, with two more unnamed Premier League clubs also monitoring Beier.
No official bid has been submitted yet, but a €40-50million offer could arrive as we move closer to the September 1 Deadline Day.
BVB’s position is clear – they don’t want to sell Beier as they believe in his qualities. Beier also wants to stay, even if Fabio Silva joins from Wolves.
