Two of the favourites for the Championship play-offs meet in France on Saturday as Widnes travel to Toulouse.
Widnes started life back in the second tier with a commanding 40-16 win over Halifax, while Toulouse slipped to a 24-16 defeat away at new look Leigh.
The Vikings visited Toulouse in The Qualifiers last season, going down 42-22, though they are much changed from that visit.
