It's the exact opposite, you don't put a price on a player in that instance. Especially not one that absurdly isn't insane in the market these days.http://www.footmercato.net/ligue1/transferts/l-as-monaco-fixe-le-prix-de-tiemoue-bakayoko_197543
According to France Football, Monaco want at least 60M€ for bakayako. Clear message from Vasyliev : they don't want to sell key players.
Man.City still looking for him according to the paper version.
Maybe it is for him, I don't know, but if you put a price on a player you can prepare yourself for him potentially going.
