Preston North End boss Darren Ferguson is planning major changes at Deepdale this summer, with defensive recruits his main priority.
Ferguson has announced that Chris Sedgwick and Liam Chilvers will not be offered new deals, while Eddie Nolan, Stephen Elliott, Neill Collins and Neal Trotman have joined Michael Hart, Richard Chaplow, Darren Carter and Neil Mellor on the transfer list.
Ferguson told the Lancashire Evening Telegraph: "We need defenders, we need centre-halves, no doubt about that.
"The goals we have given away have been an absolute joke, I'm sick of saying it.
"We can't defend, whether people don't want to, or one or two of them think they are on their way, I don't know.
"But from what I've seen over the last four months they won't be getting a move anywhere."
