Harry Kewell blamed individual mistakes for ending Crawley's Town preseason unbeaten run after they were hammered 6-0 by Brighton and Hove Albion.
Socceroo goalkeeper Mat Ryan was between the sticks for the Seagulls in the opening half but was largely a spectator as the Premier League newcomers cruised to victory at Checkatrade Stadium overnight.
The Reds have enjoyed a bright start to their preseason friendlies under new coach, Kewell, with wins over Oakwood, East Grinstead, Dulwich Hamlet and a draw with Chelsea's U23s.
But the relentless attack of Brighton proved too tougher a test for the League Two side as Solly March, Pascal Gross, Jamie Murphy, Tomer Hemed, Connor Goldson and Glenn Murray all got their names on the scoresheet.
Kewell said his overall feeling post-match was "disappointment" but he couldn't fault the commitment of his men.
"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," the Socceroo legend and former Liverpool star told iFollow Crawley.
"They don't represent a team that's been passed through and they don't represent a team that has been cut open."
Kewell added: "All the boys are working hard and that's all I ask.
"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."
