"Bristol have to go into this game as favourites, they don't lose in the Memorial Ground often."
"We know how difficult they are to beat at home but we have to go there to do a job, and know that if we can get the result we are through to the quarter final, which is a big statement for us to make."
Despite returning to training this week, Tom James has not recovered sufficiently from a throat infection to be considered for Sunday's match.
