These clubs know what they're doing. they will have anticipated the reaction of the major football organizations, and 'supporters' alike, and have solutions and answers for all. I'm pretty certain they'll retain teams in their various leagues, albeit a second string which will probably be as strong as a top 6, with overall squads of 40+ - which they'll be able to afford. They may change the names, ie Man Utd play as the 'Red Devils' in the PL, and they won't need to come in the top 4 anyway because they're already there.
