9. Paul Pogba – Juventus
Current value: £39.5m
When the young Frenchman left Manchester United nobody expected that he would have proved to be the instant hit that he has in Serie A. A number of clubs in both England and Spain are rumoured to be keen to take him away from Turin this summer, and though his next move won’t garner £100m, the next one very well might if he continues his development at another of Europe’s elite.
