The Argentine moved to Italy from Barcelona for a world record transfer fee considered to be worth more than the current value of Real Madrid's star
Former Napoli president Corrado Ferlaino claims Diego Maradona cost the club “double what Cristiano Ronaldo would cost today” after the star joined from Barcelona in 1984.
The Serie A outfit splashed out a then-world record transfer fee of £5 million to acquire the mercurial Argentine, who had previously broken the same record when arriving at Camp Nou.
Maradona would provide the inspiration for a remarkable era of success in Naples, as two Italian league titles and the UEFA Cup were captured.
