Hopefully that's the case. If Bill did decide that the price was right though I think that he'd try and shift the blame on to Baines somehow. But then at the same time I don't think that he'd want to stir up hostility (especially as it wouldn't be Baines' fault), so he'd probably play it very much as he has done with Moyes going to United.
It seemed to me that the Rodwell transfer happened in that sort of way. Jack appeared to me quite focussed on doing well for Everton and had no particular ambitions of going to a 'big' club, but he was more or less told that he was going. Fighting to stay would probably have seemed futile and it might have seemed foolish to turn down much more money and the chance to reach the pinnacle of the sport.
