What you say isn’t wrong, but what
@devilish said in regard to it is the stance most will take observing the player objectively because he was purchased and treated like a potential great of his generation, pretty much readymade (going by his Ajax showings) and ready to deliver, so he was never going to be judged as a kid, coming up the ranks - he has always been paid as though he is a bona fide elite CB and is judged in accordance with that.
He may turn it around and fulfil his early potential, if he does so for us then that will be incredible, but as of now, you can surely understand the doubts people who aren’t sold have about him? “Wages” simply doesn’t hold up because if a player is good enough, clubs will bend over backwards to accommodate them, even if it means sacrificing others or curtailing some of the future budget/expenditure.
A lot of eyes will be on him in the PL. I do sincerely hope he can deliver.
