Salford coach Richard Marshall has slammed his team’s sloppy discipline after the Red Devils lost 28-18 to Castleford.

Marshall’s men fell to their fourth Super League defeat of the season and had captain Lee Mossop sin-binned for a late hit on Friday night at the AJ Bell Stadium.

Salford have won just one league game in 2021 and the coach admitted he was fed up with his side’s tendency to give away penalties.

“We’re bitterly disappointed to lose that game,” Marshall said.

“I’m sick of our ill-discipline, I’m sick of it. We don’t want to be imbalanced team.

“Some of our penalties were stupid. I thought there were a few harsh calls in the game, but there’s no excuses.

“Some were down to a bit of tackle technique, we had a couple of swinging arms. I’m not quite sure, I think the penalty count was 9-4 [to Castleford].

“I thought we didn’t get a fair rub of the green on a few of the decisions. But at the same time we have to be accountable for our performance.

“We have to get the penalties out of our game. I’m sick to death of talking about penalties.”

The score was 14-12 at half-time and close until the final 20 minutes when Castleford pulled away.

Despite the defeat, Marshall was pleased with his side’s performance and detected signs of improvement.

“I’m not too despondent,” he said.

“There was a lot more in that performance that we could walk away with our heads held high about.

“Our first half was really good, we went toe to toe, but we couldn’t sustain that performance in the second half. But we’ll learn from that game.”
