Cooper told the Peterborough Evening Telegraph: "It's great for Darren that he's back and it seems like a good job for him. Preston are a big club with a good fanbase and he deserves his chance there.
"I suppose he will fancy a few of our players but I doubt whether he could afford them so I'm not expecting to hear from him.
"I have always got on great with him and I honestly hope he gets a good reception when he comes back here at the end of the month.
"He may have struggled for a couple of months this year but what he achieved at this club in the previous two years was outstanding."
