If City were guilty of any wrongdoing at the time, then hopefully the club now, will make sure it's completely out in the open & shame others into doing the same.
But if this guy was known to be dodgy & City were at fault, letting him be involved with the club in any capacity, then there are also plenty of others, some much more at fault, who knew about it before then & afterwards & also therefore surely someone at the FA must have known.
It's also pretty obvious there is a great big, famous youth developer, elephant in the room, who was involved in every stage of this bloke's career, & people must be able to put him away, if they give evidence. And they need to do so.
