Newcastle coach Eddie Howe was interviewed by the media and talked about Isaac's situation.
Eddie Howe said: "Of course there is some dynamic behind the scenes. The conversation between Isaac and Isaac and the club will remain private. Whatever happens, the interests of the club must be the priority."
"No contract negotiations are underway. This may be a future."
"I certainly hope he stays, but this is football, who knows what will happen in the future."
