"I think they've got a great chance of staying up," he told the Lancashire Evening Telegraph. "They've got a brilliant manager. The spirit is there, the margins are smaller at this level but they can do it. They're certainly not going to get beat by four or five every week.

"The manager has to take credit for what they have achieved."
