So Jon Palmer is the go to person who divulges every football clubs turnover, contracts and salaries. Not exactly official is it. If this is the guff you are relying on for your knowledge then you need to start to take a step back and shut up a bit more because the simple fact is that you actually don't know.
Any future questions about anything football related then I best contact Jon. But as you already seem to be in bed with Jon and take what he says is gospel what are the payment instalments, what was paid up front, how are they staggered in the future, what percentage did Stoke get, is there any sell on clause added to the deal, and what are the exact add ons and the conditions that trigger them? And where does this put Will in the salary pecking order? Shirt size and foot size would also be good knowledge to have.
Take a step back and stop talking nonsense, and someone else's guesswork at that.
