Bristol City boss Lee Johnson is demanding interested clubs get serious about Adam Webster.
Newcastle United and Aston Villa are eyeing the defender.
Johnson said, "I think the first port of call is that we understand the speculation because he's a fantastic player.
"Our stance is that we don't want to lose Adam Webster. You can never say never in football. But if you look at the values for other players flying around that sort of figure would be vastly undervaluing him from where I would see it."
