He's easily with 100k a week. I'm sure we have players less talented than him on more.
As for a release clause, let him have that too. Better that than nowt less than a year from now and the loss of a boss player who's already playing well in our current squad.
If he'd have opted for a release clause a year ago, what would we have said was fair? £20m-£30m? If that. Now look how much he could probably have gone for.
