The Warriors have tasted away wins against the Raiders only twice with just one win in 11 attempts at GIO Stadium (a 31-24 success in 1997 when former All Black Marc Ellis kicked five goals and a field goal), while the other victory was a 22-10 triumph in 2001.
"I'm not concerned about our record there," said McFadden.
"This game is about focusing on ourselves and controlling what we can control. It's obviously a hugely important match in the context of the season."
The Warriors go into the match sitting ninth on the NRL ladder after back-to-back defeats to the Broncos and Sea Eagles. They are one of six teams on 22 points. The 15th-placed Raiders have an impressive record at home overall with a winning percentage of better than 67 per cent, but their 34-18 loss to South Sydney last night was their sixth defeat in eight matches at the venue this year.
Sunday's match will be forward Ben Matulino's 147th NRL appearance, leaving him in line to play his 150th game when the Warriors host the Sydney Roosters on August 24.
The contest to be the Warriors' top try scorer this season has tightened up with Manu Vatuvei and Konrad Hurrell on 10, Sam Tomkins and Simon Mannering on nine and Johnson on eight.
