Results elsewhere meant a win could’ve lifted the green and whites out of the bottom two but Filipe Morais’ strike on 72 minutes secured the win for the visitors.
Coming close to an equaliser late on through Ryan Seager, Town’s boss was left to rue a lack of urgency from his side.
“I was happy that it was 0-0 at half time because we were a bit too passive,” he told iFollow Glovers. “I think we picked it up in the second half and had those chances that we did have, but that 1-0 basically killed us.
“We did come back again and we tried really hard but it wasn’t to be. We weren’t producing any pressure at all. We were just sliding it across the pitch.
“We didn’t let them have any chances (in the first half) or produce any shots on goal, but we didn’t have any either. We picked up in the second half, and just in that phase where we had some momentum, they scored their one.”
The result sees the gap to safety extend to two points as the Glovers head into the busy Easter period.
Only scoring twice in the last seven games, Marmon is aware of the importance of finding the back of the net.
“We’ve always required a goal to get momentum. We looked a bit scared at 0-0 or at 1-0 down and I think that’s gone throughout the season.
“When we get a goal that’s when we blossom again, but we’ve got to get that goal, that’s the problem.
“The way you should look at it is that you have nothing to lose. We’re in the bottom two at the moment so you might as well go out and play freely, but that’s easier to say than to do.”
