Charlton boss Alan Pardew is ready to sell fullback Luke Young.
Pardew said: "I appreciate that at this stage of his career he wants to play in the Premier League.
"He's a difficult price because of his age and because he's an England player but I'm sure one or two clubs will come in and he'll be interested."
Middlesbrough, Aston Villa and Newcastle have all made inquiries about the right back.
