Clermont Auvergne have dominated the TOP 14 so far this season, slipping to just one defeat in their opening nine games. Two big wins over Biarritz Olympique and Perpignan in the last two weeks will ensure they go to Stade Francais this weekend full of confidence.
Clermont then face a tricky opening to their Heineken Cup campaign having to travel to Belfast to face Ulster.
Two wins on the bounce has seen Toulouse rise to second in the Top 14. They host Perpignan this weekend before a home tie against Gloucester a week on Sunday to kick-off their Heineken Cup.
Castres find themselves on the road two weeks running as they travel to newly promoted Bordeaux this weekend before facing the Scarlets in their opening European match. Castres seven match winning streak came to an end last weekend with defeat to Racing Metro so will look to bounce back before the start of the Heineken Cup fortnight.
Racing Metro have slipped to three defeats in their last four matches, but did record a victory against high flying Castres last week. They travel to Brive on Saturday, who sit just two places below them in the table and will look for a confidence boosting win before welcoming Cardiff Blues to France next weekend.
Montpellier's match against Lyon and the Basque derby between Biarritz Olmypique and Bayonne have both been called off due to an outbreak of Mumps in the Lyon.
Montpellier will travel to reigning Heineken Cup Champions Leinster on the opening weekend, and Biarritz face the Ospreys at the Liberty Stadium.
