I actually disagree in reality that every player has their price mate, take our manager - there was zero fee that they would have sold him for at his peak. Same for United with Scholes, Giggs.
Same realistically for Kane at spurs they can effectively set such an insane valuation that they know in reality that the player has been priced out of any possibility of being sold.
Rooney being sold was a kick in the teeth, but it was effectively as the club was close to being bankrupt - and he went to the biggest club st the time on the planet with massive stability under Ferguson.
Any thought of selling to someone like Spurs is laughable, they are a media big team, have won nothing in recent memory worth anything, in fact your going back longer than for us to find a time when they where a relevant big team.
If 15 years has changed this club from the lows of early Bill selling our future to United to now selling our future to Spurs - then it's time we pack up shop, the club would be signalling that survival in the league is the current and only long term objective now.
