Grand final preview, anyone? Friday night's clash at ANZ Stadium may not be the last time these two teams play at that ground in 2018.
This match has just about everything. A Rabbitohs side that has turned itself into the best attacking unit in the competition will run into a Melbourne outfit that is gathering steam at the right time of the year.
For all the talk of AAMI Park being a fortress for Craig Bellamy's teams, their away record over the past three season is superb. They lost three away matches in 2016, one in 2017 and have three losses outside of Victoria this year.
South Sydney weren't at their best against the Eels last weekend but were still able to get the win. If they're not on the ball all night against the Storm, the scoreboard won't be as kind to them.
Key match-up: Damien Cook v Cameron Smith. After Smith's shock representative retirement denied us of a meeting between these two during the Origin series, their personal duel on Friday night will garner plenty of interest. Cook leads the NRL with 112 dummy-half runs, and many of them have had good results. Smith runs when he needs to, but it is his game management and passing and kicking skills which stand him at the top mountain. The clash of the season between a pair of superb No.9s.
For the Rabbitohs to win: When the three Burgess brothers are carting the ball up the middle of the field with gusto, Souths look like potential premiers. Cook, Adam Reynolds and Cody Walker all feed off the Englishmen. If that trio can all get over 100m running for the match, the Rabbitohs will be a great chance of winning.
Rabbitohs v Storm - Round 21
For the Storm to win: Controlling the tempo of matches is a skill the Storm have mastered. When they're ahead they're great at chewing up time with sets of six designed to force the opposition to continually come out of their own danger zone. They want to turn the match into a grind. They rarely lose when they achieve that goal.
Rabbitohs Stat Attack: Forget about the Raiders, the Rabbitohs are the best attacking side in the Telstra Premiership. They have the most tries, the most line breaks, the most try assists and the most line-break assists. The much vaunted Storm defence is facing its toughest test of the year.
Storm Stat Attack: For all the credit heaped on the Storm over the last three years, could it be possible that they are still actually underrated? A grand final loss, a grand final win and top spot on the ladder this year is a great return. They've lost 14 (regular season) games since the start of 2016. Four NRL sides have lost at least that many matches in 2018 alone.
And another thing: Craig Bellamy said no to the Broncos when he agreed to re-sign with Melbourne. That move saw Rabbitohs coach Anthony Seibold installed as a candidate to take over from Wayne Bennett when his time with Brisbane ends. A win over Bellamy will only help Seibold's future employment opportunities.
Rabbitohs: Robert Jennings was left out of the squad 24 hours out from kick-off, with Adam Doueihi named to start on the wing. Braidon Burns has been elevated from the reserves to the bench. Billy Brittain was omitted on Thursday night.
Storm: Prolific try scorer Suliasi Vunivalu was ruled out 24 hours out from kick-off. Cheyse Blair will start on the wing. Ryan Hoffman (shoulder) returns in the back row with Joe Stimson dropping to the bench. Dale Finucane starts at lock with Kenny Bromwich back to the bench. Albert Vete was cut 24 hours out from kick-off.

Petero Civoniceva's prediction: What a cracker this should be - a top of the table clash at this time of the year. The Rabbitohs have stalled a little bit lately compared to how they were playing during their winning streak, but they showed a bit of class to claw their way back and get away with a win last week But they're aren't playing as well as the Storm and that's where I'm leaning. The Storm were clinical in their defeat of the Raiders and look primed for finals football. They've been more consistent than Souths over the last month.
