Star wing Christophe Dominici declares the aim of Stade Francais Paris is automatic quarter-final qualification - and that will require winning both remaining matches.
"We know that if we win at home against Ulster on Saturday we will be going to Leicester looking for the necessary points in order to qualify," said Dominici. "That's all we are thinking about - we can't even envisage defeat next week.
"And if we do beat Ulster at Jean Bouin it will be an early England v France at Welford Road. We haven't travelled very well this season but it's a psychological thing. Look at the games between Leicester and Ulster and the difference in their score at home and away. As far as we are concerned, we conceded 20 points at The Dragons and then put 30 on them at home.
"But we can't afford to make any more slip-ups. We must win on Saturday and go to Leicester to fight it out for the top spot. I can't say that that is not on our minds - though I'm sure Ulster have a similar objective. Everyone is in a situation where two wins are vital.
"It is very tough to qualify through to the quarter-finals of the Heineken Cup - more so than ever before because every nations' teams have been strengthened.
"The Welsh teams are stronger after forming regions, the Scottish are showing for the first time that they can compete with the top teams and the Irish have been strong for a while so we have a more balanced and intense competition than ever - which is great."
