Perpignan finally had a win to celebrate, while Clermont Auvergne were too good for Bordeaux-Begles in Top14.
Clermont Auvergne moved to the summit of Top14 by beating Bordeaux-Begles, while Perpignan won for the first time on Saturday.
Clermont were a cut above Bordeaux in a 40-20 success, although the visitors' hopes were hindered by a red card for Blair Connor in the 53rd minute.
Alexandre Fischer, Peceli Yato, Paul Jedrasiak and Alexandre Lapandry each scored tries and Greig Laidlaw was instrumental with the boot.
Toulouse can reclaim top spot by beating Racing 92 on Sunday.
