I'd fine him two months wages and suspend him from the first team for a minimum of 3 fixtures. In addition I'd demand an apology to the club, squad and the fans. Then he can rejoin the squad and warm the bench for a further two fixtures.
I have to give FSG credit for holding firm and telling Barca where to go. Of course it could have been fear of Fan reaction that motivated them, but it could also have been a desire to hold on to our most creative player, so I'm given them the benefit of the doubt. Congrats FSG and well done, keep this up and we could yet become the best of friends!
However having said that, I'm not impressed by your imbecilic cock up with that hamfisted attempt to stop a bidding war over VvD. You clowns, you've left us worse off defensively leaving the transfer window than we were entering it. If that cockup costs us CL next season as it may well do, you'll feel the anger of the fans. Let's see ye sort it out in January as a bit of damage limitation, you utter clowns and incompetents.
