Paul Dickov stood by his players after Doncaster Rovers suffered their sixth home defeat of the season against lowly Gillingham.
Luke Norris’ second half brace earned the Gills their first away win in League One since March.
Curtis Main’s stoppage time penalty ended Doncaster’s 490-minute wait for a goal at the Keepmoat Stadium - but Rovers have won just one out of ten games on home soil this term.
Dickov said: “It’s frustrating, it’s angering, but I don’t think the players can be accused of a lack of effort, or not trying to score goals.
“We just need a bit of the rub of the green in front of goal, especially at home.”
Rovers enjoyed more possession and a far greater share of the chances against Peter Taylor’s side.
But once again they fell victim to the sucker punch as Noble scored twice after the restart to extend Rovers’ win-less run at home to five games.
“The little things, especially at home, aren’t going for us,” said Dickov.
“We’ve had more than 20 attempts on goal. Gillingham had two shots on target and end up scoring two goals.
“It was a similar story in our last two home games against Notts County and Sheffield United.
“We should have been out of sight by half time. If we get our noses in front we go on and win the game.
“It’s a frustrating time for us.
“It’d be nice to not play very well and start nicking points,” he added.
“We got a little bit frustrated towards the end, which was understandable.
“I think everybody got frustrated.
“But, as daft as it seems, there were a lot of positives to take from it.
“We probably created more chances on Saturday than we have done all season.
“But we’ve got to start taking them.”
