Chelsea are likely to block the departure of Fikayo Tomori on loan after an injury sustained by fellow centre-back Andreas Christensen.
The 23-year-old has barely featured for the Blues this term and he has managed only 44 minutes of Premier League football.
Hence, he has been linked with a possible loan move to Leeds United, but The Sun claims that the deal may not happen.
Christensen picked up a knee injury in the recent league clash against Aston Villa and there are fears that he could be out for an extended spell.
Antonio Rudiger has also been linked with a possible move elsewhere, but the setback for Christensen may force him to stay put for the season as well.
Chelsea will be aiming to end a three-match winless streak when they host League Two Morecambe in the FA Cup third round on Sunday.
