The former Leicester City manager is now in charge of Fulham.
The new Fulham manager, Claudio Ranieri, could raid old club Leicester City in January.
The Sunday Mirror reports (November 25, page 67) that the right-back Danny Simpson, the left-back Christian Fuchs and the striker Shinji Okazaki are each on Ranieri's radar, along with the former Leicester centre-back, Robert Huth.
All four players were staples of the Italian's 2015-16 title-winning side, although Simpson, Fuchs and Okazaki - each of whom are in the final year of their Leicester contracts - have made just one Premier League start between them this season, while Huth has yet to find a new club following his release at the end of last term.
Ranieri, who won his first game as Fulham boss on Saturday, has also been backed by the bookies to sign the former Foxes midfielder Danny Drinkwater from Chelsea.
Fulham welcome Leicester to Craven Cottage a week on Wednesday, in what will be the 67-year-old's first meeting with his old side since they sacked him in 2017.
