Caretaker boss Dean Austin has rallied his Cobblers squad ahead of Tuesday night’s game at Blackpool.
The Cobblers have five games to try and maintain their League One status, starting at Bloomfield Road.
"We are going to need something extraordinary but if I didn't think we were capable then I wouldn't have taken the job," he said.
"I really believe in the players and let's have a real go in these five games. I truly believe they are capable of doing something.
"I've tried to re-energise the players, I don't like negativity and I've spoken to the players about what they can expect from me and what I expect back.
"I had the desire as a player and I expect my players to play with that same energy and enthusiasm.
"I want to get my ideas over to the players but first you need that heart and desire."
