Celtic Crusaders will bring down the curtain on an unhappy debut Super League season at Castleford on Sunday with an insight into just what could happen in a year's time.

The Welsh club have inherited the wooden spoon from the Tigers, who have made remarkable progress in the last 12 months and, having already secured a play-off place, go into Sunday's last match of the regular season needing a point to finish seventh.

The Crusaders, dogged by troubles on and off the field, plan a fresh start for 2010 with a new home and a new head coach following confirmation that Australian John Dixon will take charge for the last time at the Jungle.

Former Great Britain coach Brian Noble is the man being touted as the man to turn around Celtic's fortunes at Newport's Rodney Parade after failing to secure a new contract at Wigan.

All that will be of little concern to Castleford, who need to complete the double over Crusaders to climb back above Catalans Dragons in the final table.

"Our home form has been a bit disappointing at times this year and, this being the last game of the campaign at the Jungle, we'd like to give our fans a strong finish to the regular season, as well as taking some good form into the play-offs," said Tigers coach Terry Matterson.

"But we would be wrong to think it's just a case of turning up. Celtic have tried very hard this season and the recent loss of some of their squad has left them stretched but they'll want to come here and give a good account of themselves."

Noble, meanwhile, believes he can sign off his three-year tenure at Wigan by guiding them all the way to the Grand Final from outside the top four.

He famously steered Bradford to five consecutive appearances at Old Trafford, once from third place, and has taken the Warriors to within 80 minutes of the Grand Final in each of the last two years.

"We're excited by what we might achieve," he said. "The sky is the limit if we play the kind of football we have been doing at times."

Wigan finish off the regular season at Huddersfield, who have been one of the surprise packets this season but are still reeling from their Challenge Cup final defeat and the fall-out.

"It will be a tough challenge at Huddersfield," said Noble. "If you look at the work done over years by Tony Smith and then Jon Sharp, they've steadily improved and they'll be stronger next season. I'm not surprised by them at all."

Huddersfield will be without two of their form players in prop Keith Mason and hooker Scott Moore, who have both been suspended by the club pending an investigation into alleged breaches of discipline in the aftermath of their Wembley disappointment.

Catalans' shock win over St Helens on Friday night has rendered Warrington's home match against Harlequins relatively meaningless, with little more than pride to play for by both teams.

However, the Londoners are desperate to halt a depressing run of one win in 11 matches while the Wolves will be keen to avenge a 60-8 humiliation at the Twickenham Stoop before parading the Challenge Cup at the end of tomorrow's match.

Matt Gafa, Gareth Haggerty and Daniel Heckenberg will all be making their farewell appearances for a Quins side lacking captain Rob Purdham, who has a vascular problem.
