Wolfsburg centre-back Maxence Lacroix is set to sign for Crystal Palace in a deal worth up to £18m, subject to him passing a medical.
The 24-year-old has less than a year remaining on his contract and has been targeted by the Eagles throughout this transfer window.
The Frenchman, who joined Wolfsburg in 2020 and made 130 appearances for them, played under Palace boss Oliver Glasner when he was in charge of the German side.
Palace have sold centre-back Joachim Andersen to Fulham in a deal worth up to £30m, while England international Marc Guehi is wanted by Newcastle.
