O’Meley, 32, says he hates ‘the English way’ of pledging to win for others, and that his teammates need to do it for themsleves on Sunday.
“It will probably sound selfish but I just want to do it for us, the boys,” O’Meley told the Hull Daily Mail.
“That’s who you really want to do it for.
“When you are on the field, with your mates behind you, you are the ones who have trained in the snow and stuff like that.
“The players say what they want the fans to hear, but really you do it for each other.
He said, “It is the biggest week we’ve had since I’ve been here in four years.
“We have never been this far in the Challenge Cup and to me the competition has been the pinnacle of rugby league over here since I have been watching the game.
“You don’t want to be looking back in three or four years and thinking that you could have played at Wembley but didn’t. You don’t want to be looking back and thinking we had our chance back in 2013 and we didn’t take it.”
