Mark Connolly knows that Tuesday evening's performance against Newport County wasn't at the standard needed to get a result.
The Reds led through his first half header but conceded the lead and went on to lose the game in disappointing fashion against the Exiles on a frustrating night in West Sussex.
"It wasn't a good performance and it wasn't good enough," he told iFollow Crawley.
"Up until when we scored the goal, throughout the opening stages of the game we were the better team.
"We had some chances but then once we scored we sat off - two set-pieces later and we've ended up losing the game and we know we have to be better.
"Especially at home - where we should be getting the crwod behind us and picking up wins. The home form was good last year and at times we struggled on the road and that seems to have reversed itself this season so it's something we need to put right."
The defender admitted that in the latter stages of the contest the side didn't stick to their principals and instead got lulled into their opponents' way of playing, preventing them from getting something from the game.
"In the second half we huffed and puffed but got dragged into the way they wanted to play," he continued.
"There were a lot of long balls and we don't play like that because we aren't that sort of team.
"Sometimes you can get away with having a bad game and draw or even win, but we did neither this evening and we didn't roll our sleeves up enough."
