Michael Duff believed his team deserved at least a point in their 1-0 loss against Crawley Town at The People's Pension Stadium.
A first half Ollie Palmer penalty saw the Robins slip to their first loss in eight games.
Speaking to the media after the game Duff felt his charges deserved more but was encouraged by the narrow margin between the two teams.
"We did more than enough to at least get a point - we thought we could have won the game to be honest," Duff said.
"It doesn't always happen like that but with where we've been and where we've come from we kept playing till the 97th, 98th minute, passing the ball.
"The players are believing in what we're trying to do and it was just that final moment with the one cleared off the line, hitting the near post too many times, and just something wouldn't quite drop for us today."
Nigel Atangana was stretchered off in the second half in West Sussex and Duff was unsure immediately after the game of the latest on the Frenchman's injury.
"I don't think there was any contact which is always a worrying sign. I think there was a concern over his achilles. I've not spoken to Gav (Crowe) about it so it's too early to comment."
