The agent of Boca Juniors defender Ezequiel Munoz has warned Fiorentina that a deal is no certainty.
There have been reports that an agreement was struck between the two clubs for the 19-year-old to come to Italy.
"There is no agreement with Fiorentina," insisted agent Marcelo Simonian on Radio Blu.
"The Viola made an offer four months ago that was rejected by Boca. If the Italians were to present a new interesting bid, then it could be re-evaluated, but it's not an easy situation.
"Will he stay at Boca? I don't know, there is also the option coming from Real Madrid."
