The Warriors - the 2008 tournament finalists - have banked 14 points from their three wins, three points clear of the sleeping French giants, and James Hook and his team-mates know another defeat will really dent their knock-out chances.

And in the wake of the thrilling 22-21 Round 3 win at Sixways, Warriors head coach Richard has identified the French club's scrum as one of the biggest threats to the 2008 tournament finalists making the last eight.

"If you are going to beat Perpignan, you've got to nullify their scrum and their maul, which we did except for the first 20 minutes of the second half," added Hill.

"And I saw plenty of opportunities to go wide. If we can do the same on a better pitch in Perpignan, then we can do some damage with the likes of Nikki Walker and David Lemi.

"If we had lost then we would have had to pick ourselves up going to Perpignan, but this victory gives a chance."

But while the Warriors believe they have some potent finishers, Perpignan's Adrien Planté is the leading try scorer in the competition this season with six.
