Yeah, can that really be legit?
Kane's stupid brother negotiated a very unimpressive £200k a week in 2018, coming off plenty of world class seasons, I doubt they make this sort of demand, unless they politely wanted to avoid saying "not interested".
Buying Kane for £100 million and paying him £500k a week for five years would amount to a combined package of £230 million (£130 million in wages) - even the most pro-Kane'ers would acknowledge the absurdity of paying that, even if we had the money, which we clearly don't.
