Leicester City are prepared to consider offers for Youri Tielemans.
The Belgium international has a contract to 2023 with the Foxes and the Athletic says there's a willingness to cash in on the midfielder should he refuse new contract talks.
Real Madrid and Barcelona are watching developments closely.
On his contract situation, Tielemans has stated: "There is nothing new (regarding my contract extension with Leicester). I am open to everything.
"The transfer market has closed, but I want to keep open more options."
