UEFA won't fine us at least. We're likely the only club to get a solo statement off of Ceferin/UEFA and the 1st one at that. In a weird way City leaving did more to topple this had City never joined in the 1st place (not an excuse btw). Whether it's accurate or not, it's plausible that had City been eager to stay then this whole thing would still be going.
We've done UEFA a massive favour, and if tolmie's right then it sounds like we were in cahoots with UEFA over the last day over our exit strategy. If there's one club UEFA won't penalise it'll be us.
The FA and the PL will do jack shit.
Internally within the club, I'd be shocked if there were any repercussions.
