What anti-competitive laws are you talking about? I am no expert in law or the FFP but FFP is there to basically restrict clubs from spending money in uncontrollable manner (duh!) and ensure clubs spend within their means etc. Several clubs over the years have already been punished by UEFA for breaking the FFP rules. AC Milan got banned from Europe last year, for example. So, it's not like the FFP is just for show. Acquired legally or not, City tampered with their accounts to get around the FFP rules. If their ban gets overturned completely, hell is gonna come for UEFA.
