The 24-year-old is tipped to be offloaded by Juve before the start of the season and the club have been in negotiations with the Viola.
Maresca joined the Old Lady five years ago from West Brom and has consistently struggled to establish himself at Stadio Delle Alpi.
He has undertaken loan spells at Bologna and Piacenza and was in-and-out of the Juve side last season.
The midfielder's contract expires next year and Juve have offered no signals that they are prepared to discuss an extension.
New coach Fabio Capello is willing to sacrifice Maresca and it appears Fiorentina could be his next port of call.
Maresca would prefer to stay in Turin but he may have little option but to accept a move to Fiorentina despite the animosity between the two clubs.
The player's only hope is to hold out for another club to come in for his services as Aston Villa were linked with a bid while Juve admitted they would be amenable to using Maresca as bait to land Udinese ace Marek Jankulovski.
