Toulon avenged their loss at Welford Road last weekend with a 23-8 win against Leicester at Stade Félix Mayol on Saturday.
An early Ali Williams try helped Toulon race into a 16-0 lead, and while the Tigers hit back with a try from Blaine Scully, Mathieu Bastareaud's second-half try killed off the visitors' hopes of a comeback.
