Munoz's minders have been coy up until now about the deal, but the youngster admitted yesterday a transfer was close.
"The more time passes the closer I am to Fiorentina, with the Viola, negotiations are advanced. My agent is still working there, but as far as I know there really is only a few details and I hope we can all end this soon.
"I do not know if I will arrive in Florence in January or if Boca will keep me for six months.
"At the moment, it is more probable hypothesis," said Munoz.
