"Personally it is the biggest game I have played at the club, it is a must win game for us in the group because we need this one to put us on track for the last two games of this group," said Jenkins.
"The last 18 months to two years we have really improved and to stand up to Stade Francais on Sunday was a real achievement and we are just gutted we did not get the try we needed in the last 20 minutes.
"The conditions were not the best but as a pack it was a good achievement to stand up to them, but in the end we lost the game so this week we have take them on again.
"It will be a much more expansive game, they want to throw the ball about and we will attack in different ways.
"Being in with a chance in the group makes us feel good, if we win on Saturday then we are in the driving seat in the group.
"We hope the crowd will be vocal, 10,000 is a great crowd for us and we hope they get behind us."
