Crystal Palace chairman Steve Parish has admitted that the club are now looking to sell young defender Nathaniel Clyne who has been heavily linked with a number of Premier League clubs.
The England Under-21 right-back is now out of contract and should a club look to sign him the they would be forced to go through a tribunal as Palace would be due compensation due to his age.
The 21-year-old has a been a regular starter for Crystal Palace for some time and has already made well over 100 league appearances for the side since making his debut back in October 2008.
Manchester United have been repeatedly linked with the defender and it seems Palace are keen to try and secure a fee rather than leaving it to a tribunal.
"We need to do a deal with Clyne," Parish told Sky Sports. "There is a bit of action in the background and we know there is a lot of interest.
"It is just about sorting out who it is best to go to and who will put the right money on the table. We're all working to get an outcome. Clubs don't want to go down the tribunal route. It is a game of cat and mouse on the fee - we've just got to let that play out."
Manchester United are short of options at right-back where they have used the likes of Phil Jones, Chris Smalling and Rafael da Silva. The Brazilian is the only man who naturally plays in that position and has failed to make it his own.
Clyne has been a regular at various youth levels for England and, despite his young age, he is already a vastly experienced defender at Championship level.
