Adrian Lam criticised his players’ attitude following defeat to Castleford last night.

The Warriors came unstuck against the Tigers after having started the season with victory against Warrington in round.

Lam lamented the stop-start nature of the contest, though admits his side only has itself to blame.

He told reporters after the game: “It was really frustrating, just a penalty-a-thon. There were 10 penalties against and no flow in the game.

“We were poor with a lot of things, our attitude wasn’t right, I’m not impressed at all.

“Four of the penalties were in front of the posts and you can’t do that when you come to Cas.

“We’ve only got ourselves to blame because our execution on the back of that was not great, we were not Wigan tonight, a lot of silly basic errors.”

Wigan return to action at home to Toronto next Thursday and Lam is clear about where improvements must be made.

“We’ve got a fair bit of work to do. We looked off the pace from the start, they tackled harder and ran harder than us.

“We got a little bit ahead of ourselves after last week. It’s an opportunity to re-think and move forward again.”
