AFC Wimbledon manager Neal Ardley told BBC London 94.9:
"We worked really hard on how we were going to approach this game.
"I'm certainly learning the hard way what this job brings.
"We will get to work next week. We haven't had many free weeks where we can do a lot of work on the training pitch.
"We're in a dogfight and we've got to make sure that we start picking up some results."
