A look at some previous landmark football transfers following Gareth Bale's 100m euro move to Real Madrid:
Johan Cruyff - Ajax to Barcelona in 1973 for then $US2 million.
The three-time Ballon d'Or winner became the first million-dollar player when he joined the Catalan side to be reunited with coach Rinus Michels. The move paid off as Barcelona went on to win the Spanish title for the first time since 1960 that season, and "Total Football" became the club's philosophy of play. Cruyff returned to Barcelona as a manager in 1988.
Diego Maradona - Barcelona to Napoli for then about $US7.6 million in 1984
Napoli's rise to prominence coincided with the arrival of Argentine genius Diego Maradona after club president Corrado Ferlaino accepted to splash cash to bring "El Pibe de Oro" to the coastal Mediterranean city. Maradona helped the club win two Serie A titles in three years and the UEFA Cup. But his stint in Italy had a bitter ending as Maradona left the club after testing positive for cocaine.
Roberto Baggio - Fiorentina to Juventus for then about $US13.6 million in 1990.
If there is something Juventus and Fiorentina share, it's certainly mutual contempt.Baggio's departure to Juventus in 1990 added fuel to the flames.For years, Baggio had been a fan favourite in Florence and a large section of ultras took to the streets to voice their anger when it appeared certain that their idol was being sent to Juventus. Dozens of people were injured in the riots but Baggio left, later saying: "Deep in my heart I am always purple," the colour of Fiorentina.
Jean-Pierre Papin - Marseille to AC Milan for 10 million pounds (then about $US19 million) in 1992.
By joining AC Milan, Papin arguably made the biggest mistake of his career. A star in Marseille, Papin was at the top of his game when he decided to leave the French league to follow in the steps of Michel Platini. In Italy, Papin struggled to adapt to the team and suffered various injuries. In 1993, he was a substitute during the Champions League final that Milan lost to... Marseille.
