All three clubs were linked with the Lazio winger during January but were put off by the £22million asking price.
Liverpool have been tipped to go back for the 29-year-old this summer but they may lose out to Inter, who are making plans for their approach already.
According to the Gazzetta dello Sport, the San Siro club are willing to offer a year-long loan package, including a loan fee paid in installments and an option to buy at the end of next season.
Candreva is an important member of the first team at Lazio and has made 23 Serie A appearances this term, scoring seven goals.
However it has been suggested that, with Candreva turning 30 in February and his contract up in 2019, Lazio may decide to move him on in order to raise funds.
