Chelsea are reportedly only prepared to loan out Antonio Rudiger if the defender pens a new contract at Stamford Bridge.
Having fallen down the pecking order under Frank Lampard, the centre-back will be able to leave the Blues before the end of the summer transfer window.
Tottenham Hotspur, West Ham United and Paris Saint-Germain have all been linked with an approach for the Germany international.
While Chelsea are open to allowing the 27-year-old to depart on a temporary basis, The Mirror claims that they first want to agree fresh terms with the player.
Rudiger, who is said to have a £20m asking price, currently has less than two years remaining on his contract.
Chelsea are likely to request that any loan bid includes a mandatory option to buy in 2021.
