Harry Kewell was disappointed that his side didn't compete with Port Vale for the duration of Saturday's game.
The hosts found themselves 2-0 down inside the opening half an hour, and the Australian was keen to point to the need to focus for the entire game.
"When you talk about football, you talk about it being a game of 90 minutes," he told iFollow Crawley.
"I thought Port Vale were good in the first half, and we knew they would be strong at set-pieces.
"I think we maybe fell into a bit of a trap with how they wanted to play - but then in the second half we really came out and improved."
Indeed, the side were far better in the second period and created a host of chances - as well as pulling themselves level.
The Head Coach revealed that he had some words with them at half time, but insisted he saw plenty of promising signs despite the final result.
"I told them to believe in themselves more," he continued.
"We had some positive moments, and I thought Enzio (Boldewijn) and Jordan (Roberts) were excellent.
"But there's plenty to build on - it's disappointing that we lost but we'll learn and there were encouraging signs."
