Thorman is hoping for a better performance than last week’s 30-10 defeat at Dewsbury Rams.
He said: “It was disappointing that we didn’t seem to be up for the game against Dewsbury.
“For whatever reason we started poorly in defence, which was really disappointing. We’ve done a fair bit of work looking at defensive specifics, but we missed too many one-on-one tackles and we didn’t deserve to win the game.”
He added: “Halifax are one of the best teams in this competition. We’ll respect them, but at the same time we have to have a much better attitude and go into it a bit more aggressively.
“It’s our first home league game and we’d like to think we can put in a good performance.”
Fax coach Karl Harrison is preparing his side for the realities of playing at York.
He said: “It brings its own tests because of the side of the field.
“It’s not the biggest playing field, so it will be a very tough battle and we’ll pick a team accordingly.”
