He spent four years as Newcastle United boss until 2014.
The Magpies sit 19th in the table, one point adrift of safety with just three league games in which to save themselves.
The first of those three come at St James's Park tomorrow when United host the Eagles, who themselves probably need a victory to guarantee their top-flight status, with Pardew's side eight points clear of 18th-placed Norwich, who have a game in hand.
Pardew spent four mixed years at the North-East club, securing Europa League qualification in his first season before enduring somewhat average campaigns after that. However, the 54-year-old made himself perfectly clear when discussing Newcastle's survival hopes.
“I want them to stay up,” Pardew said as quoted by The Mirror. “Those players are close to me, a lot I managed there and I've been through a lot with those guys, on the pitch and off it too with one or two of them.
"I'm desperate they stay up. But my job is to get the three points for Crystal Palace. That's what my professional head will do.
“It is what it is. I can only be professional with my team. That's my professional head. Emotionally I want them to stay in the division, but that doesn't mean I want to let Norwich down, or Sunderland down. I wouldn't be doing my job.”
Pardew left the club last January to join Palace. Like Newcastle, he enjoyed a brilliant first eight or nine months in the job but things gradually went downhill, to the point where they have managed just one league win in 2016.
That being said, he has led them to an FA Cup final, where they will face Manchester United next month.
