If anything, this just shows how important the Sky revenue is to clubs outside the top 5 in England. I'm guessing that in 30-40 you'd probably find the rest of the Prem clubs.
I don't really see the matchday revenue as being the key to breaking into the top 5. The top 5 are so far ahead it's clear their revenue is coming from many other sources.
Maybe you need to win an Asia Cup?
