Richard Hill's Bristol Rugby need a win against French champions Stade Francais Paris or they face falling behind the pace in Pool 3.
And Hill was frank in his assessment of the French team, "There aren't too many weaknesses, they are the French champions," he said. "They are certainly very streetwise."
"They are a top quality side, but maybe not playing at their very best at the moment. We have to hope we can catch them when they are a little bit complacent."
"Toulouse weren't quite at their best against Edinburgh last week and Edinburgh could possibly have won that game - so we have to hope that Stade Français arrive from Paris thinking they are going to come into Bristol and just walk away with the spoils."
"We will have to fight and scrap for everything and see what we can do. They have 25 internationals in their line-up, so whichever 15 they pick, you know you are going to face 15 top-quality internationals."
"The crowd should be a big help. I can't imagine too many Parisians will work their way over to Bristol, so there should be a really good crowd of Bristolians there. It would be lovely to sell all the remaining tickets between now and Sunday and make sure that place is absolutely rammed full of Bristolians."
