La Rochelle's South African winger Dillyn Leyds scored as they beat Clermont 26-13 in the French Top 14 on Saturday before next weekend's Champions Cup semi-final with Exeter.
Toulouse celebrated their first win at Clermont since 2002 on Sunday with a 32-13 victory that consolidated their seven-point lead at the top of the French Top 14.
The irony of their 14-24 loss to Clermont at the Stade Marcel Michelin on Saturday evening was that their biggest lesson is one they've already been exposed to this season.
