Chelsea will not accept any offers, permanent or loan, for Andreas Christensen.
However, Gary Cahill could be allowed to leave Stamford Bridge.
Christensen has expressed his frustration at falling down the centre-back pecking order under Maurizio Sarri, with David Luiz and Antonio Rudiger establishing themselves as the Italian's preferred duo.
However, the Dane will not be allowed to leave Chelsea under any circumstances, according to the Evening Standard.
The same can't be said for 32-year-old Cahill, who is out of contract at the end of the season.
Several clubs have shown an interest in the Englishman, including AC Milan, Manchester United and Aston Villa.
