Way over paid for City...I don’t know if it was maturity or a football intelligence thing. I’m only posting my opinion of why Pep didn’t trust him enough as he’s never spoken about it. My guess was Sane would give up posession by making the wrong choice at the wrong time and it was that inability to learn that frustrated Pep.
If thats the case I don’t think its about maturity or even application it may just be a skill he hasn’t got that Pep needs.
