The Viola contacted Guarente’s agent about a move last summer.
“I know nothing about it,” agent Giovanni Bia told Tuttomercatoweb.
“I can just say that there was contact [with Fiorentina] over the summer, but nothing more.
“Guarente is having a good season and it’s normal that he is being tracked by many important teams.
“And Italian clubs are not the only interested parties. I reckon that Atalanta will not offload him in January.
“I think that it will be difficult to hold him back next June, particularly because we all know Atalanta’s policy.”
