Premier League season tickets have gone up by three and a half times the rate of inflation over the last 35 years - and Chelsea are one of the worst offenders.
The average season ticket price for a current top flight club in England cost £53 back in 1981.
That's equivalent to £183 in today's money when adjusted for inflation, an increase of £131.
However, the actual average cost for each club's cheapest season tickets is £513 according to figures taken from the BBC price of football survey, an increase of £459.
That's 3.5 times the price of what you would have expected if season tickets had gone up in line with inflation.
Chelsea's season tickets have increased by just under six times what you would have expected.
Chelsea's has gone from £50 in 1981 to £750 today. That's 5.7 times more than the £123 increase you would have expected based on inflation.
When it comes to inflation busting season tickets, the Premier League's worst offenders are Bournemouth.
Theirs has gone up by six times the amount you would have expected based on inflation.
Back in 1981 a Cherries season ticket would have cost you £35. Adjusted for inflation that would be £121 today, an increase of £86. However, the club's cheapest season ticket in 2015-16 was £550, an increase of £515 from the 1981 price, six times the expected £86 rise.

Norwich's and Newcastle's have gone up by five times the expected amount, Manchester United's have gone up by 4.7 times the expected amount, Tottenham 4.6 times and Arsenal 4.5 times.
Aston Villa are the club whose season ticket price is closest to what you might expect based on inflation.
The cheapest adult season ticket at Villa Park would have set you back £335 at the beginning of this season. In 1981 it would have cost you £57. Adjusted for inflation that would be £197 today. It means that Aston Villa's season tickets have gone up by just less than double the expected amount.
