Your basing your whole argument on rumour, its only rumour he wanted parity with the top earners and its only rumour that that is why he even left, as far as anyone knows he may of just been waiting to see who comes in for him and jumped ship earliest possibility.. What we do know for sure is that Pienaar got us a couple of mil, Lescott got us full price so from a club perspective its far worse.
However they go its better the club gets what the player is worth. If they all went the way you suggest, leaving us guessing as to whether he will sign, constantly telling us talks are close, then going for almost nothing.... you seem to forget he didn't see out his contract either and left for Spurs with time remaining.. then we would be without any means of making money as none would go on a transfer.
But there you go, I guess it depends how much contract is left when the team comes in.. if its only a few months and the club have no choice but to take it then its okay, if its a few years and the player has no choice but to force it then it isn't.
Personally I prefer Lescotts because we got money for it.
