Colombia international Marlos Moreno had been linked with Inter, but Fiorentina are now showing interest in the Atletico Nacional man.
The 19-year-old attacking winger has been hitting headlines with his performances for Colombia at the Copa America.
In recent weeks there had been talk of a bid by Inter, but SportItalia claim Fiorentina have entered the fray.
Atletico Nacional want around €8m for Moreno, who scored three goals and provided three assists in just nine Copa Libertadores games for his club.
It’s believed that before swooping for Moreno, Fiorentina must first sell either Giuseppe Rossi or Khouma Babacar.
