Analysis - what to expect
Warrington's win at Wigan last week wasn’t pretty but the two points were significant for the Wolves. Despite them missing out on the Super 8s, they are getting key players back in their squad and appear to be producing better performances with it. The Wigan game allowed them to show some defensive steel; the 10 points they conceded is much better than their average of 25 points per game over the course of the season. On the other hand, Widnes' loss last week meant that they have conceded 76 points in their last two games. The Vikings have only won five games this season and it looks like it will remain that way until the Middle 8s, with the home side having too much here.
