The 35-year-old made his European debut against Perpignan back at the start of the 1998 tournament and almost 15 years on the ambition is as strong as ever - Saturday's winner facing an away semi-final against either Perpignan or Toulouse.
"Stade Francais will be an extremely tough challenge but we have to make sure we come up with a plan to counter what they do and carry on in Europe," said Stringer.
"The reason I came over to Bath in the first place was to prove to myself and to others that I could still play at the highest level and European rugby is exactly that.
"I am not the type of person that is happy to be sitting at home on the fringes and I am at my happiest playing and I still have that ambition.
"I think my time at Bath has gone really well so far and this is another step up again against Stade Francais on Saturday who are a quality side.
"These types of big games are the reason that I came away from friends and family in the first place and I hope it continues and we get the right result."
