The Penrith Panthers will be looking to avenge their 16-10 loss to the South Sydney Rabbitohs in the qualifying final that put them on the hard road to tonight's Grand Final.
For Panthers' hooker Api Koroisau losing any game hurts, especially in the finals.
He says the Rabbitohs put on an A grade defence to stop them during the qualifying final but this has put them in good place for what is to come tonight.
Koroisau says they will need to be positive and play better footy.
Koroisau is the only player in the current Panthers line-up that has tasted a Grand Final victory while playing for the Rabbitohs in 2014.
He featured for the Rabbitohs against Canterbury in 2014 alongside Adam Reynolds, Alex Johnston and Tom Burgess.
The last time the Panthers lifted the NRL title was in 2003 while the Rabbitohs last title win was in 2014.
The NRL Grand Final is scheduled for 8.30 tonight.
