Huddersfield forward Eorl Crabtree insists the Giants can put their woeful Super League form behind them in a concerted effort to reach Wembley.
The Giants go into the second Carnegie Challenge Cup semi-final against Warrington at the City of Salford Stadium on Sunday in freefall, having won just one of their last eight league games to drop from top to seventh in the table.
"The good thing about sudden-death football is you only need a decent game," said the England prop, who is Huddersfield's longest-serving player.
"We proved at the beginning of the season that we can beat the top teams, we need to take that belief into this game."
Crabtree, who was rested for the 52-6 hammering at the hands of Castleford after playing for England in midweek, says the Giants can take encouragement from the Tigers, who responded to a heavy defeat by bottom club Widnes just seven days earlier.
"Cas had been in terrible form but suddenly came out and hammered us," he said. "Sometimes that's as simple as it is."
The game is a repeat of the 2009 final won by Warrington, who have triumphed in the last seven Challenge Cup meetings with Huddersfield going back to 1933.
The Wolves also knocked Huddersfield out of the play-offs last year and won 32-22 at the Galpharm Stadium in February.
"We always seem to be playing them," Crabtree said.
"We know a lot about them. They've got some great players and some players in great form but it's probably more about ourselves and putting in a decent performance."
