The 26-year-old is poised to complete his reported €4 million switch to the Artemio Franchi on Friday evening, subject to the completion of a medical
The Primeira Liga outfit made the announcement to the Portuguese Stock Market on Friday afternoon, and the Chile international is currently in Florence undergoing a medical.
Fernandez was left out of the Sporting squad for Wednesday's Pepe Super Cup against Belenenses and his agent, Alejandro Santiesteban, revealed less than 24 hours later that he was in talks with La Viola over his client's reported €4 million switch to the Artemio Franchi.
The former Villarreal man is considered a key member of Ricardo Sa Pinto's squad, despite his persistent injury problems, but he only has one year left to run on his current contract with the club.
Fernandez, who was born in Argentina but has now racked up 50 caps for Chile, arrived at the Jose Alvalade from El Madrigal during the summer of 2009.
