Paris - Toulouse consolidated their place atop Pool 3 with a hard-fought 12-9 victory over Glasgow in the European Champions Cup on Saturday.
Sebastien Bezy kicked four penalties, two in each half, to three by Glasgow from flyhalf Finn Russell and his replacement Duncan Weir (2).
The result left Toulouse with 16 points from four wins from four games, with Bath now in second, six points adrift, after picking up a bonus point in their 32-12 victory over Montpellier on Friday.
High-profile convert Sam Burgess made his full Bath debut in the win, setting up the first of his team's four tries at their Recreation Ground home, but it was winger Matt Banahan who stole the headlines with a hat-trick.
