Juventus have signed Argentina striker Gonzalo Higuain from Napoli for 90 million euros ($98.89 million), the third highest transfer fee ever paid, Reuters reported. "I can confirm that the contract has been deposited with the League and the deal has been done," Napoli spokesman Nicola Lombardi told Reuters on Tuesday, adding that the fee will be paid in two installments. The Turin-based club triggered the release clause for the 28-year-old, who still had two years to run on his contract, Napoli added later on Tuesday in a statement. Higuain's transfer fee is the third highest paid, after Gareth Bale moved to Real Madrid from Tottenham Hotspur for 100 million euros in 2013 and Cristiano Ronaldo joined the Spaniards from Manchester United for 94 million euros in 2009. Last season Higuain scored a record 36 Serie A goals in 35 games for Napoli, who finished runners-up as Juventus won a fifth consecutive title. He joined Napoli in 2013 after spending six years at Real. The news that he was poised to join Juventus caused anguish among Napoli fans, who gathered in Naples city centre on Saturday to tear up pictures of the Argentine and set fire to replicas of his number nine shirt.
