Win the next six games and prove your doubters wrong: That's the message from Bulls chairman Chris Caisley after the Super League leaders' depressing defeat at Warrington.

And he promised full support for coach Brian Noble if he felt key selection changes were needed to boost the side in the bid to clinch top spot ahead of the play-offs.

"I can't remember us playing as badly as we did on Saturday but I have to say it is worrying," admitted Caisley.

"We have seen this situation before where the side has started the season off like a house on fire and then faded when it really mattered.

"I don't know what the reasons for our performance on Saturday were but it was totally unacceptable and I can assure the fans we are not taking it lightly.

"It wasn't so much the fact that we lost, more the way that we lost that was so disturbing. We completely lost our composure and I'm sure Brian and the coaching staff realise that as much as anyone.

"If we play like that in our last six games we will lose them all. But I am confident that if we get back to the way we were playing earlier in the season we can will them all. If we do that we will finish top and that has to be the aim.

"I just don't want to see all the hard work go to waste and I will do all in my power to ensure that it doesn't."

Meanwhile Noble and his players were re-grouping at training today and could be boosted for Saturday night's visit to Leeds Rhinos by the return of England trio Jamie Peacock, Paul Deacon and Stuart Fielden who all missed the shock 18-14 defeat at Wilderspool.

Fielden is the major concern having missed the previous game against Halifax too.

"Stuart picked up a bad dead leg against Leeds and it is taking some time to heal," explained Noble. "It is one of those injuries that will be OK again when he wakes up one morning.

"It would be nice to have him back against Leeds but we will have to wait and see how he progresses this week.

"Paul Deacon took a knock on a knee and an ankle playing for England last week and Jamie had a bit of a problem with his arm but I expect them to be available again."
