The graph below shows how the mega-money deals of Luke Shaw and Adam Lallana compare to previous transfers.
Although Adam Lallana's move to Liverpool is yet to finalised, it looks virtually done, hence its inclusion on the table.
The adjusted figures are based on an average of three per cent inflation in each year since the original deal took place, and then rounded.
Alan Shearer's move to Blackburn Rovers is included as it was the British record at the time in 1992.
That deal demonstrates the difference in inflation between the Premier League and the 'real world'.
If Premier League transfer deals had only increased by roughly the rate of inflation in the economy at large, that deal would be less than £7m today.
Instead, the record deal between two British clubs currently stands at £50m, which Chelsea paid Liverpool for Fernando Torres in 2011.
Gareth Bale's £85.3m move to Real Madrid from Tottenham in 2013 is the biggest deal involving a British club.
