Closed shop and the end of season tickets and price breaks for fans are an inevitability at the top level IMO - the Americans and the Saudis aren’t buying clubs for the amount they are for anything other than a guaranteed return and a way to squeeze as much money out of them as possible. A fan from down the road isn’t paying what a tourist will pay for a seat or what they will pay in the club shop 38 times a season.

The only thing left is to quibble over the details and when it happens, but I think it’s more likely that teams are playing mid season games regularly abroad within the next 5 years than not.
