The Athletic reported that Brentford's offer for Byer to Dortmund was rejected.

The offer could have broken the £37 million transfer fee paid by Brentford to Bournemouth earlier this month, and it is reported that the London club will not raise the offer for the 22-year-old striker.

As Brentford pursues Byer, the team's forward Visa is seeking a transfer to Newcastle, and the Magpies have rejected the offer for the forward twice.

Due to uncertain future direction, 29-year-old Visa will continue to miss Brentford's game this weekend after missing the first two games.

Brentford coach Case Andrews said: "My position has not changed, there has been no progress. He will not play against Sunderland, I will focus on players who are in a stable state and have no business troubles."
