#10. Luke Shaw: £30 million
Manchester United moved heaven and earth to get their hands on Southampton left-back, Luke Shaw last year. The young Englishman cost the Red Devils 37.5 million euros in what is the highest fee paid by any club for a left-back. However, England’s most successful club is unlikely to feel bad about parting with a substantial amount considering the fact that the youngster has really done well ever since he arrived at Old Trafford. Under Jose Mourinho, Shaw has improved a lot as a player and we’re likely to see him grow stronger in the coming years.
