With a home quarter-final the prize for the winners, the flanker is looking forward to the early start of knockout-style rugby.
“You kind of expected it to come down to one of these games,” Clark told SaintsTV. “It’s a huge occasion for us at home this week; an exciting game and one you want to play in for sure.
“Being at home is definitely an advantage for sure but they’re full of great players and they caused us a few problems at their place so we’ll have to prepare properly and play flat out."
Following a try scoring performance at Ospreys, workaholic Clark - who added a combined 26 carries and tackles for good measure - added that the side are keen to ‘kick on’ after a tough few seasons in Europe.
“We got to the final [Heineken Cup in 2011] and were disappointed with that. We haven’t really kicked on for the past three years and that’s a frustration.
“It is nice to be where we are in our group and to have a chance of going through and hopefully getting the home quarter-final, but we know it’s going to be a big job on Saturday.”
