My two cents, when it comes to the question of "why buy a second-tier football club?" - remember the 1980s? There was a period when Japanese companies were buying up American and European ones left and right, in a huge, sudden burst. It was for money, yes, but also for political and cultural reasons, to build and project soft power.
China's doing the same thing now in a number of fields - and in football, that means huge new networks of clubs, managers, agents, coaches, players, etc., etc., being bought wholesale in Europe. Mendes know there's a lot of money to be made here, by acting as an intermediary for the new money in the east and the old infrastructure in the west, as all those massive new soccer schools open up with thousands upon thousands of scholars.
I have no idea if that means good or bad things for Wolves. No chance - at all - that we'll be intended as a feeder club for, say, AC Milan, and these people will want to get us up into the top flight (and, eventually, Europe) ASAP. That said, it also sounds like we're about to become part of a massive, well-funded Chinese plan to establish the country as a soccer superpower. Something maybe a bit similar to New York City FC's place in City Football Group, perhaps, within that kind of transnational club network. Not unlikely to sign great players, but also with owners who intend to permanently be swapping players between teams within a single empire for a larger purpose. (CFG's being projecting UAE soft power.) But then we could also be beneficiaries of the first generation of world class Chinese players, which is probably between five to ten years away. Who knows?
