Newcastle rejected Perch bid this week
The Evening Chronicle says Pardew snubbed a bid from an unnamed club for Perch on deadline day.
He said he has been encouraged by the ex-Nottingham Forest captain's recent contributions.
He said: "I would like to have had a defender, but Perch did well at Brighton.
"You have to say that when he has come in he has done OK. He has boosted me a little bit on that front."
