Just wanted to add this article I stumbled on on the NY Times website:
https://www.nytimes.com/2019/07/24/sports/psg-uefa-ffp.html
In summary, Yves Leterme let PSG get away with it, Cunha Rodrigues (UEFA) went ballistic, but Yves Leterme said his objection was too late.
Yves Leterme is behind City's punishment. I would have thought the above action by the same man would set a precedent of how alleged inflated deals are dealt with (ie ignored). I think it totally undermines everything he had said about City. Hopefully, City can use the information the NY Times based this on.
