If Chelsea don’t get them signed off they’ll sue, plain and simple. Never underestimate how litigious US people are, they serve lawsuits like we do cups of tea. Can the PL tackle them, City, Everton, Forest, Leicester all coming at them?
I can see now why we’re quietly letting it all play out as I doubt the PL can afford / will want to spend a significant portion of their administrative expenses battling their own members.
