9) Ronaldo

Internazionale to Real Madrid – €46-million (2002)

Before injury and weight issues blighted the end of his Madrid career Ronaldo was the undisputed best striker on the planet. One of the capital-club’s original Galacticos, in his first season Ronaldo scored 30-goals in all competitions as the team won the 2002-3 La Liga title. This would be the first and last major title for Real Madrid as the Galacticos experiment would fall apart after the departure of manager, Vincente Del Bosque, and a number of the club’s less glamorous players. Despite this lack of trophies, Ronaldo would be voted into the Real Madrid Team of the century and Hall of Fame following his departure.
