Totally disagree an unhappy player a new stadium to pay for and new players to buy it would be silly to try and drag it out as city could just move on and leave spurs in the lurch.
Am a Spurs fan - think he will leave by the end of the window and wish him good luck, very good player and a great servant. However would be over the moon if he stays -WC year so he will want to perform. We get a player we rate at £50M+ on wages of around £70K pw - in the open market a player £30M alternative (no idea who this will be) to replace would want £100K plus. We have always spent what we have brought in regarding player sales so unlikely to make much difference to the stadium debt.
Think Levy & Pochettino would be over the moon if we keep him.
