Sheffield Eagles players have been warned not to let their guard slip after scoring tries.
Coach Mark Aston is demanding an end to the sloppy play that crept in during the big 70-28 Challenge Cup win over London Skolars.
He wants a much tougher mental approach when they travel to Workington Town in the Championship on Sunday.
Aston says his team can score points but too often lack the “respect and attitude and discipline” he demands.
“I’m not particularly happy because we have talked about this every week,” he said.
“We scored 70 points (against Skolars) which is great and we looked good and we looked classy at times but to let 28 points in isn’t what I am about and again that’s down to our attitude.
“The amount of mistakes after scoring a try was an embarrassment.
“That’s no disrespect to London but we just knocked off, didn’t care, didn’t respect them and let some soft tries in.”
Aston rested some senior players for the Cup game and was pleased by the performance of the young players who came in with prop forward Jack Blagbrough claiming a hat-trick.
He added: “Plenty of positives – it’s not often a front rower gets a hat-trick. There’s a bit of work to do - not a lot of dramas. It’s not about defensive structures or what I’m showing the lads it’s about attitude.”
Workington Town are coming off a 27-10 defeat at Hunslet Hawks, last weekend. That followed two previous defeats.
