Dunne said: "We could have taken something from the last two games but we have to look to Tuesday now and Gillingham in the Johnstone's Paint Trophy.
"We've had our backs to the wall over the last two weeks and I really felt we would come out with something from both games (against MK Dons and Leeds) but we haven't. We got the response but we fell short, not by much.
"It's been an emotional day for everyone and we honestly believed we could win but we ended up chasing the game in the end. It took a goal like that to beat us, against a team that is top of the league."
