I don't really see what's going to be achieved by being massively unprofessional like this, it just hurts both the club and player. Look at Evans who even when available for a bargain price none of the top clubs would touch him with a barge pole after his antics last season despite bidding 5, 6 times that last summer.
If he wants to move on, ok, but giving that interview was seriously ill advised, and to leave like this would be in the most unprofessional manner possible. If you want to leave that much at least have the decency to hand in a transfer request. But that means forfeiting some money of course so that won't happen.
