New signing Marcus Hahnemann, recently signed from Fulham on a free transfer, has impressed since arriving at the club - earning the right to the number one shirt.
According to manager Pardew, Phil could soon be leaving the club.
"Phil has been a great servant to the club. He's had two-and-a-half years as this club's first-team keeper but he is upset about being left out," said Pardew.
"I expected that, but unfortunately he has made it clear he wants to get away. I didn't expect that kind of reaction but that's what he wants."
"There has been no formal transfer request."
