"It's still open in the next window."
The 27-year-old finished as the club's top goalscorer last season with 16 goals and Pardew has revealed that he has since spoken with the player after comments released from his agent hinted at his unhappiness and willingness to seek a move away from Sports Direct Arena unless things changed.

"Sometimes it's out of his control and out of my control.
"But we know each other well enough, and I've got no problems with him, because he is a team player who wants to do his best for the team. He has always been like that."I just think the agent stuff was people saying things they shouldn't say, really. It doesn't really affect myself and Demba, because we've got a very good relationship."
