Brentford manager Uwe Rosler called on his players to become more ruthless after a 2-0 defeat at Carlisle sent them crashing to a second successive loss on the road.
Rosler's side failed to turn possession into goals after forcing the pace for large parts of the match.
But they came up against a resolute Carlisle defence and the Cumbrians took a big step towards safety with a first-half header from Sean O'Hanlon and a second strike after the break by striker Mark Beck, his sixth goal of the season.
Rosler said: "It is important to keep your nerve. We are not performing as we can and we need to be more ruthless and have more belief.
"We are showing too many nerves at the moment. The first goal should not have happened and with the second goal we are killing ourselves, but we also have to score goals and show more belief and aggression in the final third.
"Our crosses weren't 100%, but sometimes strikers have got to make a bad cross into a good cross."
It was a first win in seven games for Carlisle, which had a lot to thank central defensive pairing O'Hanlon and Danny Livesey for an uncompromising display at the back.
Carlisle manager Greg Abbott said: "Trotta and Wright-Phillips destroyed us last time we played Brentford, but Beck outshone both of them. No-one has probably heard about Mark Beck, but they will have heard about him after this.
"This is probably the best result since I became manager of this club. It's the proudest I've been. We have a group of players performing well above their station at the moment.
"We are coming out of a tough situation. No-one shirked anything and there was effort and determination."
