This Friday sees one of the most eagerly anticipated derbys of the season as St Helens take on Wigan at the DW to try and clinch third spot. Wigan have won all matches between the two teams this season and aim to keep that 100% record. Rivalry is proving no barrier to the Joining Jack charity however, as both teams will be wearing special shirts bearing the charity's logo. SLTV caught up with coaches Shaun Wane and Mike Rush, Saints prop Louie McCarthy-Scarsbrook and returning Warrior Tommy Leuluai.
