Ruben Olivera is undergoing his medical in Florence as he nears the completion of his move from Lecce to Fiorentina.
The 28-year-old attacking midfielder has been allowed to leave the Stadio Via Del Mare for the Stadio Franchi this month.
Olivera first moved to Italy in 2002 when the Uruguayan international was snapped up by Viola rivals Juventus.
The South American has also appeared for Sampdoria and Genoa in his career. He is expected to sign a contract until June 2014.
