There have already been a number of huge transfer fees paid for teenagers this summer so CaughtOffside has picked out the most expensive teenage XI of all time for your enjoyment.
GK – Thibaut Courtois – Genk to Chelsea, £7.9m
David de Gea would have made this list had he not just turned 20 upon completing his move to Manchester United and it looks to be a fine deal for this young goalkeeper judging by his recent performances on-loan at Atletico Madrid.
