To be fair, none of that precludes Red'n'Blue's scenario from having substance. i.e: if Leeds want CMS over RMc and are able to get him, then they don't make him the offer he's holding out for, and he leaves. If they can't get their preferred choice, then they up their offer to RMc and he stays...
Who are 'Brighton' in this context? If you mean 'some Brighton fans' then you are right - some would be upset if we swap CMS for RMc. Others would be delighted.
