Swansea City assistant boss Alan Curtis says the club need to investigate their "calamitous" defending after their 5-4 victory against Crystal Palace.
Despite taking three dramatic late points, Curtis says an analysis of their defence performance is needed.
"It's certainly something we will be discussing with the players," Curtis told BBC Radio Wales.
"We will have to look at the way we defended and try to come up with ways to try to improve it.
"We know there's a lot of work to do. Some of the goals we conceded, it was calamitous.
