The 27-year-old Senegal international this season has looked a shadow of the man who scored 13 times - and often in spectacular fashion - in his first 14 appearances for the Magpies after completing a £9 million January switch from Freiburg.
Cisse heads for Stoke with only three goals to his name this time around - one of those unwittingly off his backside - and with Pardew attempting to nurse him through a run of indifferent form.
Pardew said: "I am talking to him and trying to calm him, tell him that he's still he same player and we are still very confident in him.
"It's only been a small period if you compare it to, say Torres' period, but you would have to say it's something we are going to have to keep an eye on because we don't want it to end up like poor old Torres has ended up at times.
"He's a great player, Papiss, and we want to get the best out of him."
