“A couple of years ago, with the aid of Graeme Riley’s immense database, I devised the Transfer Price Index Coefficient (TPIC), as a means of measuring transfer success rates. Our work together with TPI – which converts all transfer fees to ‘current day money’ with an index-based inflation model – led to so many possibilities beyond its initial aim, as it evens up the most expensive signings of, say, 1994 with 2003 and 2014; so that rather than £5m – which was the transfer record 20 years ago – you can ‘see’ it as a value that makes sense in today’s market. (Chris Sutton’s move to Blackburn now equates to £28.7m.)” Tomkins Times
