James Roby says Saints last-gasp win over Leeds is all the motivation they needs to topple the Rhinos once again.
The two old foes face each other on Saturday weeks after a pulsating Super League encounter which saw the men from Langtree Park nab the spoils in the dying seconds courtesy of a stunning Tommy Makinson strike.
And St Helens ace Roby is confident Saints will again emerge as victors when the two sides meet what is undoubtedly the pick of the Challenge Cup fifth round.
“Everything has been going well, we have had a few lucky escapes and obviously we are undefeated (in the cup) so far,” said Roby.
“We managed to scrape through with a drop goal against Huddersfield in the last round but there is a hell of a long way to go in the season.
“There are always areas of your game that you can improve on, be it individually or as a team. Every match is tough and you have to be at the top of your game to win.
“On the one hand you are not so happy because you have not performed to the best that you can, but on the other hand you are pleased because you showed a desire and effort to win.”
St Helens have enjoyed lots of past success in the Challenge Cup, winning 12 of their 21 final appearances, with former Man of Steel Roby being a part of the victories in 2006, 2007 and 2008.
However, they have not always been as successful against Leeds, losing all four of the pair’s Grand Final meetings but Roby says the team has what it takes to break the spell, particularly having beaten the Rhinos in the league only a few weeks ago.
“We have got a good blend of experience and youth in the squad. In the Leeds game, when we played them the first time, a lot of young lads came in and took their chance,” added Roby.
“They stepped up to the plate and we got the win – it can only be good for the club in the long term.
“The Challenge Cup is ideal for knockout Rugby League but ideally you don’t want to play yourself into that position in the first place.
“We have played so many big matches against them in finals and grand finals. They are a great side with international players across the board. There is a group of players who have been there years but we know that we are up to the job.”
