I noticed his name today, too, so had a dig about. UEFA rules seem to be that no one owner can have a controlling interest over 2 clubs, but they can have an interest in more than one. The BBC article says Crotty is a Director of Ineos, which wouldn't necessarily mean that he'd then become a director of Chelsea if Ineos bid was successful (but it seems likely). Also not sure if Crotty is already a director at Nice (which Ineos also hold ownership stake in). His investment in Aberdeen was (I think) reported as personal contribution, rather than on behalf of Ineos, which would likely also make a difference from a regulatory point of view. It's a bit of a strange scenario, though...
