Boss Steve McNamara admits Bulls fans have a crucial part to play in the club's bid to reach Old Trafford.

He has challenged them to bring on the noise against Warrington tomorrow night - and then watch his champions rise to the occasion.

Bulls enter the Engage Super League elimination play-off in confident mood having cantered past Salford at Grattan Stadium last Saturday.

Another victory will see them just one step from a sixth successive Grand Final but the Wolves are equally as bullish, having stunned Leeds to reach the second round for the first time.

The visitors were backed by 2,000 raucous fans at Headingley but that number will TREBLE tomorrow as Warrington go play-off crazy.

The club have laid on more than 30 free buses to ship in a walloping army of 6,000 supporters - their biggest-ever travelling contingent in Super League.

That promises to generate a real buzz at Odsal, with McNamara looking forward to home supporters adding to the mix and bringing out the best in his troops.

"It's absolutely massive," he said. "The fact that they are bringing those fans is a major boost for Warrington.

"If the Bradford fans respond accordingly - which I'm sure they will - turn up in their numbers and be very vocal, what it does is create a huge atmosphere.

"I know for a fact that when our players smell that atmosphere at Odsal they generally respond accordingly. I think it's fantastic news for us that so many fans are willing to come across from Lancashire." Season-ticket holders can claim a £2 discount on tickets bought before 5pm this evening. Meanwhile, loose forward Jamie Langley is struggling to prove his fitness in time for the clash, meaning McNamara is likely to name the same 17 that swept past Salford.
