Just lifted the following from Wikipedia https://en.wikipedia.org/wiki/Premie...0the%20Premier

Parachute payments are unique to the English game and currently see clubs relegated from the Premier League receive a percentage of the equally shared element of broadcasting rights each Premier League club receives. This percentage drops progressively over a three year period – 55% in the first year, 45% in year two and, if the club was in the Premier League for more than one season before relegation, 20% in the third year.
Same article says we'd have had £41.6m last year, £34.9 this so £80m is close but we get nothing next year as we were only in the league for season.
