For Harlequins RL Head Coach Rob Powell the Challenge Cup will always invoke special memories. Rob was at Wembley in 1998 to see his home town club, Sheffield Eagles, cause one of the biggest upsets in rugby league history when they beat Wigan.
So looking ahead to Friday night's clash with the Leeds Rhinos in the Fifth Round of the Carnegie Challenge Cup at Headingley does the Cup still mean something to him and his players?
"Yes it certainly does to me and the rest of our club," he said. "It gives a club like ourselves an opportunity to go somewhere, do something and get some recognition and play some decent games.
"It also gives us an opportunity, especially as we've not been going that well in the league, to re-focus and get some energy for something different."
Rob believes that knock out football requires a change in attitude and even different tactics. "Because it's 'win or lose', the mentality of the blokes going into the game is different," he explains. "It's not like the league where you can talk about building on performances and trying to get a run of form together -with this, you're either in it or you're not.
"There's a bit of doing what's necessary to win a game. Our tactics will be slightly different because our blokes know you've got to put everything in."
Quins have won at Headingley already this season so does that make a difference?
"Yes it does, it's the same group of people, albeit not quite playing to the potential they were in that game. I think we showed enough that night, and even in the games recently, that we've got a style that can challenge Leeds and we'll go up there with lots of confidence that having beaten them once, we can do it again, "We definitely feel we've got the capability to do a decent job on them."
The Rhinos have had a few injury problems but given the depth of their squad Rob expects a tough game but what about his Harlequins team who haven't won against Super League opposition for a while?
"We're not training with any less intensity, the blokes are fully on board, unfortunately when things aren't going well we're not dealing with it as well as we did earlier in the season.
"That's a confidence thing and we need something to grab hold of to get that confidence back and that's going to take something on the field. They've probably stopped believing a bit in their own abilities and we need to get that back."
The team will be without both Karl Pryce and Lee Mitchell, who are cup tied, but Rob has been impressed with the youngsters in the squad. "One of the positives this year has been the kids. Olsi Krasniqi was one of our best performers against Wigan and guys like Ben Bolger and Dave Williams have done really well this year - they're a more ready to play than they were in years gone by.
