A lot is the obvious answer - United, City, Arsenal, Tottingham, Chelsea are all in the top 10 most expensive, alongside clubs like Real Madrid and the likes. Even guessing you'd think those teams, housing the best players in the world, are worth quite a lot.
The above mentioned are also the top paid (alongside Liverpool) from TV money/revenue every year. Even more so when you consider how every promo is basically from those teams' best moment and best players highlights, with the rest barely getting a mention.
That's without the obvious under the table money for other things that the FA definitely receives but hides from prying eyes.
So maybe not even "a lot", probably closer to "bend over backward for, priceless".
