Analysis - what to expect
This is arguably the biggest game of the season for both of these sides. Widnes gave themselves a glimmer of hope in their quest to pull themselves up the table and challenge for a place in the Super 8s with their win over Leeds, and back-to-back wins could be the turning point in their season. The run of five Super League defeats came to an end for Catalans in their game against Hull and they know a win here would consolidate their place in the top 8. Widnes will be buoyed by their win on Monday and should win again here, extending their unbeaten run over Catalans in the league to five games.
