Crystal Palace manager Roy Hodgson admits every player has their price amid speculation surrounding Aaron Wan-Bissaka and Wilfried Zaha.
Manchester United and Manchester City are interested in young right-back Wan-Bissaka, while Zaha has been linked with a shock return to Old Trafford.
Speaking ahead of Wednesday night's clash with Tottenham, Hodgson said: "Every footballer has his price.
"Just because they have a contract here doesn't mean they have their feet nailed down here. The club is in no way advertising them as sellable objects.
"The good thing for me is one has a five-year contract, and one has a four-year contract.. Our aim is to start next season with them in our team, and if not, I hope the club feel the offers received for them were enough and worth taking."
