The agent of Luca Cigarini refuses to rule out a move to Juventus for the Sevilla midfielder.
Cigarini pledged his commitment to Sevilla last week.
But agent Giovanni Bia says: "Although no negotiations have taken place yet, Cigarini is certainly a name that Juventus would like - especially if Sissoko leaves.
"Sevilla want to keep him for the time being, but let us just wait and see whether there is a chance of a January return to Italy."
