Having lost out to Manchester City for Danilo, Antonio Conte has turned to the Italy international.
The Chelsea boss wants someone to challenge Victor Moses for the right wing-back spot.
Conte failed to land the versatile Candreva in the January transfer window — but is confident he can get his man this time.
SunSport understands Inter are reluctant to sell the 30-year-old, who they bought from Lazio last summer for £18.7m.
Inter would rather offload Ivan Perisic to Manchester United — but the Red Devils have baulked at their £48m asking price.
Candreva is willing to move to Stamford Bridge after the Italian giants disappointed last season.
Conte worked with him when he was Italy boss and the prospect of linking up again, at a club challenging on all fronts, would be tempting.
