4) Brighton – 25.5
The Seagulls have become renowned for investing in young talent.
Having sold the likes of Moises Caicedo (22) for a British record £115m, the South Coast club have reinvested the money in players such as Bart Verbruggen (21) and Carlos Baleba (20).
They have also recruited teenagers Valentin Barco (Boca Juniors) and Ibrahim Osman (FC Nordsjaelland) for the start of next campaign.
Using data to guide them, Brighton are able to pick up gems for relatively low prices and turn them into star names.
