Fulham have made a £20m bid for Crystal Palace centre-back Joachim Andersen.
The Eagles value the 28-year-old Denmark defender - who joined Palace from Lyon in 2020 for about £20m - at nearer to £40m.
Fulham have been looking to increase their defensive numbers after Tosin Adarabioyo joined Chelsea following the end of his contract and Tim Ream moved to Charlotte FC.
They had a bid rejected for Aston Villa defender Diego Carlos earlier this week but completed the signing of Jorge Cuenca from Villarreal.
Andersen spent the 2020-21 season on loan at Craven Cottage from Lyon.
