The January transfer window sees the Senegalese ace’s £7million release clause in his contract open up again and although Pardew is confident of keeping him, he wants to end the worry and frustration that comes with having such a player at his club by either securing or selling him in the summer.
"Really and truly this window is the key, I think, because if Demba goes in this window, it will cause us a problem,” the Toon boss said.
"I think he will stay, but there's a possibility he could go because of the clause that's still in force.
"In the summer, I won't let it run until the summer. I'll do something about it.
"We will either move Demba on or we will secure him in the summer."
