Brentford will only sell Bryan Mbeumo if the "deal is right" - and they have not yet ruled out the forward staying, says director of football Phil Giles.
Cameroon international Mbeumo is the subject of serious interest from Manchester United, who have had two offers for the striker rejected - the second of which was worth up to £62.5m.
Mbeumo, 25, wants to join United and is understood to have told the west London club that.
Giles told BBC Sport: "There's not so much [progress with Mbeumo].
"He had a fantastic season, we expected big interest in him, we have had big interest in him.
