As I’ve alluded to, and I don’t believe I am alone in this, a far far greater concern is the member of the club’s medical team who is going around giving out personal health details of club employees to people off the internet.
Some people want Jack back, some don’t. Comme ci, comme ça. In the great scheme of things, and of this club’s forward trajectory, it doesn’t make an earth shattering difference either way. Great players have always been replaced etc.
What is a major concern however is the leak of Jack being a functioning alcoholic that “the club have stated”. This goes directly to the heart of the club and if what you say is true, and I have no reason to doubt you, then City has a major issue within the walls of the club that we have somebody in a position of trust who is gossiping about player welfare.
As the person who was given the news that Jack is a functioning alcoholic it is, I would say, incumbent upon you to report this to the club hierarchy, and if said leaker was a member of the medical team (as presumably they are by dint of them diagnosing Jack as a functioning alcoholic - not something a non-medical person would be able to diagnose) then further reporting to the relevant professional boards would also be prescient.
