Look at Leeds United story, they were gone, and a huge Leeds fan ended up buying the club, surely got a lot of investors but they came back to premier league by sheer love of the club and doing whatever they can for it. I feel like this is not really about Chinese, Arabic, Russian or whatever, it is about not being native to the land and actually rooting for the club since a little child, THOSE kinds of people will actually do their best for the club.
