Chelsea want to sign Crystal Palace and England centre-back Marc Guehi.
The west London club are looking for a replacement for Wesley Fofana, who Enzo Maresca confirmed could miss the rest of the season with a serious hamstring injury.
Newcastle made several attempts to sign Guehi last summer but could not agree a fee with Palace.
The 24-year-old started his career at Chelsea’s Cobham academy before joining Palace in an £18m deal in the summer of 2021.
Another option being considered by Chelsea is to recall Trevoh Chalobah from his loan at Palace.
