South Sydney meet Penrith in Sydney tonight with the winner to move a win ahead of the other on the NRL ladder.

Both sides have shown glimpses of form while struggling for consistency of effort on and off the field.

Rabbitohs five eighth Cody Walker (pictured)  has been a shining light for the Redfern club since making his debut in 2016 and he says he thinks a more consistent approach to training and improving combinations with the likes of veteran John Sutton has been a vital component in his improved on field performances for the side.
