The Dons go into Saturday's clash with Fleetwood needing a win to stay up, and Ardley is confident they can pull off a great escape.
"Every player has to put in a shift and we will give it everything," he said.
"We have come a long way in the past four or five months. We had an awful lot of ground to make up and that has been the problem.
"But we have made great strides and the team have to put in one more big effort to get us over the line. If we put in one more good performance then we can stay up."
