Wigan head coach Shaun Wane was critical of how his side finished their sets following the 27-10 defeat against Castleford at the DW Stadium on Thursday.
The Warriors are without a win in their past four games after defeats to Hull FC and Leeds, as well as a draw against Huddersfield.
“The way we ended our sets wasn’t good enough,” he said.
“The only time people have finished their sets and made a lot of tackles against them were Salford and they got turned over so that was the aim tonight but we just didn’t do that.”
There was a point late on where Wigan could have reduced the deficit to just four points entering the final five minutes, but Wane thought they never deserved the right to get near the Tigers.
“If we ended our sets miles better then we’d put them under pressure and we score right at the end and it’s a closer game but we give the interception away,” he added.
“We didn’t deserve to get close to them to be honest.”
Wane admitted Castleford, who have dropped just two points from a possible 16 since the start of the campaign, are genuine Grand Final contenders but also highlighted their good luck with injuries so far.
“They are a real threat no question, but every team’s going to have injuries and we’ll see how they cope with that,” he said.
“We’ll see how they are at the end of the year, but at the minute they’re flying so well done to them.”
