Reading your comments and Datura's put me in mind of Rooney. Not contradicting what you are saying, that is obviously the norm and Roon is an example of that 1% exception. But still. Shows the players dont have all the power, even if they have most of it. Modric has some time left on his contract too i think, so in some ways Spurs are in a stronger position than we were.
And I absolutely agree with Harry's logic, they shouldnt be selling their best players, they should be reinforcing the squad, looking to break into the top 4. You can make the Ronaldo comparison but the difference was that was an exception, United dont tend to sell their best players to rivals, as the Rooney saga illustrated in the end. Spurs have been a bit of a feeder club for us for years, it is not like Modric is an isolated incident, it was Berbs before that and Carrick before that. If they show that level of ambition and bring in new players I dont think Modric would kick up a huge fuss.
