I would make an effort to have a good relationship with everyone. I would give a chance to any player to prove, both in training and on the pitch, if they are worthy. Fresh start with everybody, this includes Sancho, if he trains well and plays well he could reignite his career. No second chance for Greenwood though, I require a certain moral integrity. Players like Antony and Rashford might be staying on the bench for a while if they keep performing like they are. Bruno can remain captain but he needs to stop whining like a little schoolgirl for everything that happens on the pitch. If he can’t I’ll simply make the oldest player on the pitch captain until I find a suitable candidate.
I would stop playing players out of their natural position. No more Bruno RW or other bullshit like that. I would address the injury crisis ASAP, there must be something wrong with their training regime that is causing too many injuries.
Players who want to leave in January can do so only for a fair price. New players arriving will have their wage more dependent on caps, performances and other stats.
I’m Italian, you put Meret as 10th and Provedel as honorable mention. You completely forgot Vicario which is better than both IMO and Donnarumma who is currently our national team’s starter (which I disagree with but I still consider him good).
Onana had a terrible start of the season, Sommer maybe a few years ago would have made the list but not now, Pope could maybe be an honorable mention, Spain has has at least 4 or 5 keepers that are way better than De Gea.
Few names in random order you didn’t even mention: Diogo Costa, Gregor Kobel, David Raya, Giorgi Mamardashvili, Unai Simon.
A personal favorite which I think is underrated: Wojciech Szczesny.
