The Melbourne Storm have long been regarded as one of the best defensive sides in the competition, so the Warriors might be concerned to hear that has been the area of focus for Craig Bellamy's side this week.
The two rivals go head-to-head in what has become a bit of a regular Anzac Day clash in recent years and the Storm will be focusing on the work they need to do without the ball.
Despite beating Manly last start, the Storm were disappointed in conceding 26 points against a side not in the top eight.
Impressive utility back Cameron Munster says there has been a clear focus on lifting their standards ahead of Tuesday's game.
"We were still a bit disappointed with our defence," Munster said of the win over Manly. "We pride ourselves on our defence here and we let in 26 points and we haven't done that in quite a long time.
