Huddersfield captain Kevin Brown believes his side can send out a message to the Stobart Super League big guns with victory over leaders Wigan.
The unfancied Giants will leapfrog the 2010 champions into top spot if they can complete the double, following their 20-16 victory at the DW Stadium in the opening round back in February.
And Brown says confidence is high as his side look to break the traditional stronghold on the Super League top spots.
"Wigan, along with a few other teams, have been the benchmark, winning both competitions in the past two years, but we beat them at the beginning of the season so there is no reason we can't do it again," he said.
"You want to play well every week but you especially want to play well against the top teams and I think so far this year we have proved we can do that."
Wigan coach Shaun Wane, shocked by his team's casualness in their earlier defeat by the Giants, insists they will be better prepared this time and has pinpointed former Wigan favourite Brown as the man they need to watch.
"I have watched quite a lot of Huddersfield games and they are playing really well, especially Kevin Brown," he said. "We need to make sure we stop them playing.
"We faced the Giants at the start of the year and we got beat mentally. We were not prepared to work hard that day and that can never happen again."
