Argentina striker Gonzalo Higuain has reportedly sealed a move from Napoli to Serie A rivals Juventus on a four-year contract, with the club's announcement of the transfer said to be taking place on Tuesday.

According to Sky Sports News, the 28-year-old underwent a medical in Spain last week and has moved to the Italian champions for a fee said to be in the region of £75.3m, enough to trigger his release clause.

Higuain, who reportedly attracted interest from Arsenal and Atletico Madrid, joined Napoli from Real Madrid in 2013 and had two years remaining on his contract in Naples.

He ended the 2015-16 season as the top scorer in Serie A with 36 goals and scored 91 times in 146 appearances for the Partenopei.
