There are no rules once you reach a certain level. Them, City, PSG, Barcelona just do what they want. The thing that annoys me in particular with Chelsea is that, while I’m not saying they should’ve been out of business or anything, there have been no repercussions for the Abramovich situation, indeed it’s ended up brilliantly for them with the new guy splashing the cash even more readily.
For a bit they were a fully Russian entity under sanctions, their assets (including the players) were Russian assets, and the government were openly saying their money, and the money they spent to get where they are now, was corrupt money. Shouldn’t that have had some repercussions? Maybe forced to forfeit some assets? Nope, onto the next owner, debts wiped, spend spend spend again.
