Eagles’ new signing Misi Taulapapa, a Samoan international winger who has previously played for Cronulla, could make his Sheffield debut on Sunday.
Sheffield coach Mark Aston said: “If Misi is comfortable then we will get him in against York.
“Having a player who has made 40 plus appearances in the NRL is exciting.”
Thorman said: “We just concentrated on the stuff that we’ve been doing all through pre-season. We concentrated on a good performance and the result will look after itself. We were very good defensively against a Leigh side that threw an awful lot at us.
“There were loads of positives for us but we also know there is still lots of improvement that we need to make. If we can tidy up offensively and be more clinical then we’ll score some points some this year and be quite an entertaining side.”
He added: “All we’ve talked about since I came here is about doing things right and being as professional as we can.
“It’s looking good but we don’t want to get carried away.”
