The Reds will chase their first league win of the campaign against local rivals Huddersfield in a game that will rekindle memories of the 2-2 draw at the John Smith's Stadium in May when both sides escaped relegation, and midfielder O'Brien has urged supporters to stick with David Flitcroft's side.
"I think it's important we gel together again and they understand what we're trying to do," O'Brien told Press Association Sport.
"They realise we do have a game-plan. We do press teams and hound teams, but against Southampton in the League Cup, they have top, top players and our plan was to draw them on a little bit and then counter-attack.
"I think in the first half the fans got frustrated that we weren't pressing so much and getting close to them, but that was our game-plan, it's not as if nobody turned up.
"I know it ended up 5-1, but for 60 minutes we were well in the game. It's just about everyone being on the same page, that's all.
"Last season the fans were absolutely brilliant and drove us on and they were the reason why the last-day draw at Huddersfield was so special as well."
