He's already on 11 goals in all comps this season. The numbers he's putting up are just frightening; and the only thing that stunts these numbers is a serious injury.
In a hypothetical scenario, if he wants circa 400-450k at his next club then we have to pay it; because there will be plenty of other clubs willing, they'll find a way of doing so and making it work. He's already the best striker in the world (of course that's a subjective take but I don't see how it's arguable) and he'd arrive here as our most important and valuable player. It's an unpalatable truth that some on this forum might not accept, but we're still some way behind the likes of Madrid, Barcelona, Bayern in terms of prestige and allure. We can't expect generational players like this to run through brick walls to come to us if we're not going to pay a little more than the aforementioned clubs. Because if it comes to us offering pay parity with those others, he's choosing one of them. Simple as that.
He's the one we have to change tact for next summer.
