Stade Francais must gain a winning bonus-point on their first visit to Parc y Scarlets. The French giants are playing catch-up after losing twice to Pool Three rivals Harlequins last month.

A double from Stade captain Sergio Parisse gained maximum points in the 37-15 win in Paris. The Scarlets will be aiming to end a dismal run of 11 European games without a win.
