The South Sydney Rabbitohs face one of their most gruelling tests of the season this week when they take on the Melbourne Storm in a first against second blockbuster at ANZ Stadium.
With so many big players going up against each other and top spot on the NRL ladder on the line, this action-packed match up will have views intrigued for the full 80-minutes.
With so much going on here are four key points to keep an eye out for.
Old foes collide
The battle between the two captains is the price of admission alone in this Round 21 clash, with Rabbitohs leader Sam Burgess and Storm skipper Cameron Smith set to go head to head once again.
When these two come together it's always an intriguing contest as both possess an incredible competitive nature and will stop at nothing to help their side acquire the two points.
These two have had some many famous battles over the years for both Club and for Country.
The battle of the wings
Both teams have been electric in attack this season and have been the benchmark all year. It means that those watching this epic battle will bear witness to what is expected to be a sensational battle on the wings.
On one side you have the duel between young winger Campbell Graham and State of Origin flyer Josh Addo-Carr and on the other, you have NRL's leading try scorer Robert Jennings up against Fijian powerhouse Suliasi Vunivalu.
While they may be playing on opposite sides on the field both Jennings and Addo-Carr will be looking over at each other as they both eye the top try scorers gong.
Then on the other side of the coin, giant wingers Graham and Vunivalu will be trying to outdo each other, as they are both capable of scoring some pretty spectacular tries.
Home ground advantage
For the first time since 2014, the Rabbitohs will finally have the opportunity to play the Storm on home turf.
The last time Souths beat Melbourne was in 2013, which was on home soil and since then it has been a five-game losing streak for the Red and Green with matches being played out of Perth of Melbourne.
With the opportunity to play the Victorian side in front of their home crowd, the Rabbitohs will for sure be out to grab a rare win against a side whom they have only beaten four times.
While there may be a collection of point scorers and game deciders on show, the contest in the middle of the park will bring the house down, especially the battle between the two number tens George Burgess and Nelson Asofa Solomona.
Both men are sheer mountains and you can expect their impact to be colossus.
Whichever forward comes out on top here will go a long way in helping his respective side getting the upper hand.
