Southern Districts and Northern Suburbs meet in the second preliminary final at Forshaw Rugby Park on Sunday afternoon. Both sides recorded strong wins in the opening week of the finals and take plenty of momentum into the match. Southern Districts - Keys to victory Midfield attack Southern Districts centres Apo Latunipulu and Denny Godinet were brilliant against Randwick last week. If the powerful pair can repeat that effort and get Souths over the advantage line, halfback Dewet Roos and the big Rebels forward pack will be very hard to stop. Set piece When things get tough, Southern Districts like to revert to their scrum and did so successfully against Randwick however Norths and Waratahs prop Angus Ta’avao may have something to say about that on Sunday. On a windy afternoon, the Rebels line-out was inconsistent last weekend, something they must fix ahead of Sunday’s clash.   80-minute performance Like Sydney Uni, Southern Districts tend to drift in and out of matches
