I think that is the gist of the change in tune from him.
If the club tell them they have a valuation adn they know no-one will pay it then therefore getting rom more money here is in his players interest. If come next season he has added another 30 goals to his tally then the likelely hood of him then being bought as per the valuation would increase. I would imagine the main point of negotiation however would be a release clause put into the contract as it would then shift power back over to the player if indeed a club then matched the clause rather than simply our valuation
Don't think British teams do release clauses so to speak.
