Biggest Super League win: 76-6 (v Widnes, 2012).
Biggest Super League defeat: 60-12 (v Leeds, 2006).
Ground and capacity: Gilbert Brutus Stadium, Perpignan, France, 11,500.
2012 average attendance: 9,280 (up by 893).
Record Super League attendance: 11,122 (v Wigan, 2006, at Stade Aime Giral) (also drew 18,150 for visit of Warrington to Barcelona’s Olympic Stadium in 2009).
Out: Clint Greenshields (North Queensland), Setaimata Sa (London Irish RU), David Ferriol, Sebastien Raguin, Ben Fisher (all retired), Cyril Stacul (Pia).
In: Zeb Taia (Newcastle), Brent Webb (Leeds), Olivier Elima (Bradford).
Odds to finish top: 22-1.
Prospects: The loss of the hugely influential Scott Dureau through illness for the first few weeks of the season could be crucial but new coach Laurent Frayssinous has enough talent at his disposal to ensure his side are competitive.

Captain: Andy Lynch.

Odds to finish top: 12-1.
Prospects: Many are expecting the arrival of Gareth Ellis to turn Hull into potential champions but coach Peter Gentle will be hoping his failure to land a new top-quality scrum-half does not come back to haunt him.
Coach: Craig Sandercock (since November 2011).
Captain: Michael Dobson.
2012 finish: 10th.
2012 leading scorers: tries - David Hodgson 16; goals - Michael Dobson 103 ; points - Michael Dobson 243.

Odds to finish top: 80-1.
Prospects: The departure of Blake Green leaves a huge hole in the Robins’ attacking armoury and much will depend on the impact of the club’s trio of overseas newcomers. They are sure to be competitive but could once more miss out on the play-offs.
Coach: Brian McDermott (since November 2010).
Captain: Kevin Sinfield.
2012 finish: 5th.

Out: Shaun Lunt (returned after loan spell to Huddersfield), Brent Webb (Catalan), Weller Hauraki (Castleford).
