Stade Francais will be odds-on favourites to continue their impressive start to Pool 4 after their success at Ulster. 

The two-time finalists never looked troubled in Belfast and now aim to extend their 16-match winning run in Paris. 

The Scarlets threw away a commanding lead to lose at home against Harlequins on matchday one and must produce the game of their lives to pick up something at the Stade Jean Bouin. 

Stade hammered the Welsh region 49-3 on their only previous meeting in France in the 1998/99 season.
