Harry Kewell insisted that individual mistakes proved costly in Saturday's 6-0 defeat to Brighton & Hove Albion at the Checkatrade Stadium.
The Premier League side ended up running out convincing winners in the side's second home game of pre-season, and the Head Coach pointed to specific moments in the game costing his team.
"My overall feeling after that is probably disappointment," he told iFollow Crawley.
"I understand they're a Premier League side, and Chris Hughton has them playing fantastically well.
"But I think the goals represent mistakes on our part.
"They don't represent a team that's been passed through and they don't represent a team that has been cut open."
Kewell was keen to emphasise that the two other matches this week, along with the continuing pre-season schedule as whole, represent a chance to make ammends for the result against Chris Hughton's men.
"All the boys are working hard and that's all I ask," he continued.
"We gave minutes to some today - and we'll give opportunities to more on Wednesday at Bognor Regis and back here next weekend against Portsmouth too.
"The beauty of football is that there's always another game to put it right - and that's exactly what we'll now be looking to do."
