3points if you look at the Italian guy who bought Leeds when they were in the Champ, then he's made a great profit when you compare his selling price(s) to his purchase price. However, difficult to tell without further analysis about how much he had to spend (or borrow) to generate that profit.
But it's clearly the model that any "financial investor" looks to take. Buy low, sell high.
As long as the club don't get caught like QPR did with Briatone and Ecclestone and then Fernandes as owners. While bills were paid the players purchased and salaries given make the recent transfer strategy here look well defined and managed.
