After the defeat to Rochdale, Cobblers boss Jimmy Floyd Hasselbaink is looking for a response from his side heading into Saturday's game at AFC Wimbledon.
"We need a reaction," he said.
"Everybody was down after the weekend and we want to put that right with a good performance.
"I am somebody who takes things to heart and we didn't do ourselves justice against Rochdale.
"We were on a good run before the weekend and now we need to try and put another run together.
"Neal Ardley has done a brilliant job at Wimbledon and he has a competitive team there but we need to concentrate on ourselves and our own performance. It needs to be about us and what we do."
