David Vaughan said Nottingham Forest were sloppy in their play in the defeat against Blackburn and need to improve for the trip to Cardiff on Monday.
The Reds lost to a late Tommie Hoban header and Vaughan believes Forest need to do better when they make the trip to South Wales.
He said: “We were disappointing on the day and credit to Blackburn, they got the result they wanted but it was a disappointing day for us.
“They came with a game plan to limit the chances we can create but we didn’t play well, we were sloppy throughout the whole game and we didn’t keep the ball well enough and it is something we need to improve for the next game.
“We looked a bit edgy in the game and it showed in our performance. We have got to try and eliminate that and try and concentrate on our game and play well.”
The gap to the relegation zone is now two points after the defeat and Vaughan says it is up to the players to pull themselves away from trouble.
He said: “It is a two-point gap now; we could have got it to eight which would have been a big gap with four games to go. We have left ourselves in this situation so it is up to us to get away from the bottom three.
“I think it is good to have a game so quickly afterwards; to get it out of our system and to try and put the wrongs right on Monday and hopefully we can put in a positive performance and get the right result.
“It wasn’t one of my best games and with Monday in mind I think that was a factor [coming off], but it was disappointing to come off and disappointing that we lost in the end.”
