However, Aston insists his side need a major improvement if they are to have any chance of claiming silverware this summer.
Aston said: “We were rubbish (against Keighley) and I don’t know why we keep playing like this.
“It gives me sleepless nights because we talk about playing to the plan but we’re not doing it.”
Morrison said: “It’s pretty grim, but the spirit is there and everybody’s going to do their best.
“Nobody’s going to expect us to win this week, so we’ve got nothing to lose.”
