The former Italy international is no longer in first team plans of Antonio Conte and he is widely tipped to leave at the end of the season.
Quagliarella could have left the Bianconeri in the January window, but he surprisingly rejected several lucrative offers.
One of those proposals was submitted by Lazio, with the Biancocelesti likely to return for the experienced forward despite agreeing to sign Filip Djordjevic from Nantes.
However, they could face stiff competition from Fiorentina, who are also believed to be interested.
Fabio Quagliarella joined Juventus from Napoli on a six-month loan, before the Bianconeri opted to make the transfer permanent.
The 31-year-old has since scored 23 goals in 82 Serie A appearances, while netting 6 times in 11 Champions League outings. Quagliarella has 25 Italy caps to his name, but he last appeared for the national team in September 2010.
