Another player who brought Barcelona a then-world record transfer fee (but, yet again, a man they'd surely have liked to keep on the payroll), Ronaldo went on to enjoy a staggeringly successful career, establishing himself as one of the finest strikers in the history of the game. At the tender age of 20, the Brazilian mimicked his countryman (Romario) by enjoying a ridiculously prolific first season, bagging 34 goals in 37 appearances under Bobby Robson. He was ultimately swayed by Inter Milan, before making a £30,000,000 move to Real Madrid, where he surprisingly only won a solitary league title. He did, however, cement his status as an all-time great.
