Chelsea have agreed a £20million deal with Crystal Palace for Marc Guehi, Goal reports.
The England U21 defender spent the 2020/2021 season with Championship side, Swansea, which allowed him to get regular game time.
Guehi is undergoing a medical with Palace and will sign a five-year contract with the South London club.
Chelsea are willing to let the Ivory Coast-born star go, as they are already well-stocked at centre-half.
The Blues have, however, included a sell-on clause within the terms agreed with their domestic rivals.
They also have the option to match any offer tabled in future transfer talks.
