Bradford Bulls coach Brian Noble hopes his 'big occasion players' are up to scratch tonight.
Having lost to Leeds twice already this season - in the Challenge Cup at Valley Parade and in the Super League at Headingley - he admitted today: "We have to concentrate for 80 minutes.
"We have played really well throughout in four or five games this season, and need to put another one of those together again."
Noble is looking forward to the task as much as his players, however, and predicting a thriller, he said: "It is a massive game. It is without doubt now the biggest derby in rugby league and it should be fantastic.
"There will be a big crowd, a tremendous atmosphere and a lot of emotion - all the ingredients are there for a classic."
He added: "I'd like to think that the players would not treat this any differently to any other game and that they prepare just as well every week, but the biggest games bring out the most competition in the best players.
"They like the big games and the big occasions and there is nothing bigger than this fixture!
"I am excited about it and there is an element of that in the players as well. It is what the game is all about."
Noble isn't forecasting a Bulls victory though and wanted to give the Rhinos due respect, saying: "I am pretty optimistic that we will play better than in our two meetings earlier in the season, but let's give credit to Leeds.
"I have said all along that the better team beat us on the day in both those encounters, and we need to make sure we are the better team tonight or we won't win again.
"We have to do things that will trouble them and, by the same equation, we have to negate some of their offensive prowess, and they have plenty of that!"
The Bulls have named a squad of 19 that includes former Leeds junior Richard Moore and second row Rob Parker.
However, Noble said: "Richard is still getting pain from his big toe injury and he must be a doubt."
l Bradford Bulls' clash at Halifax Blue Sox has been moved forward a day to next Friday (8pm), but will still be covered by Sky TV.
