Luke Patten believes Salford need to improve defensively despite a three-match unbeaten run in Super League.
But they have conceded 84 points in those three games and full-back Patten, 32, told BBC Radio Manchester Salford must be tighter in defence.
"We shouldn't be letting that many points in and it is definitely something we'll talk about," he said.
Patten scored one of six tries in the 34-30 win against Catalan last Friday, a game in which Salford trailed 20-0 and also played for a short spell with 11 men.
"We're the sort of team that need to take our chances and get confidence from that," added Patten, who will retire at the end of the season and return to his native Australia. "That's what happened towards the end of the Catalan game.
"All year, we've been a team that have been in games and have just needed a bit of luck to go our way.
"The Castleford game (on Sunday) is a huge game for us. Three wins on the bounce would be beautiful."
