8. Ronaldo - £19.5m | Barcelona to Inter Milan in 1997

Ronaldo's status as the best player in the world was secured having won an unprecedented cup double with Barcelona and the Copa America with Brazil.

Inter shocked the footballing world by spending a small fortune to lure the Samba star to the San Siro.

Having got off to the best possible start with the Italian giants after enjoying UEFA Cup success, Ronaldo suffered a serious knee injury in 1999 which curtailed his Inter career before moving on to Real Madrid in 2002.
