Brentford head coach Dean Smith accepts top scorer Scott Hogan will leave if the Sky Bet Championship club's valuation is met before Tuesday's transfer deadline.
Hogan has been omitted in recent weeks following speculation of a move to West Ham, who have so far fallen short of Brentford's valuation, which is understood to be £15million.
And the 24-year-old could miss Saturday's FA Cup fourth-round tie at Premier League leaders Chelsea due to the lack of game time resulting from the uncertainty surrounding his future.
"We would let any of our players go anywhere for the right money, because everybody has a value at any club," Smith said.
