The Roosters stand between the Warriors and a momentum swing into the back end of the season.
A victory would be a massive boost but the quality of the performance on Sunday is just as important.
Not many expect the Warriors to prevail - the Roosters are an intimidating prospect, particularly at home - but who knows what is now possible with the Auckland club?
They've been building steadily over the past three games and their performance against the Storm was top notch. Now it needs to continue; the result may not go their way on Sunday but the performance needs to be solid, to keep up the momentum.
The Roosters are a tough proposition. Their line speed on defence is incredible, particularly on the outside. A lot of teams try to go around them but that usually doesn't work; you need to go through them and control the ruck to have any chance. The Warriors should also throw in the occasional short kick to keep them guessing and negate the rapid line speed.
