Warriors head coach Richard Hill accepts they have to rely on others while he gives chances to players pushing for regular starts.
"It will give an opportunity to those that have been sat on the sidelines and are desperate to have a go," Hill said ahead of the return fixture following their 90-3 home win against Rovigo.
"There are some very good players in there and it will be their turn over the next few weeks.
"However, we are going to have to hope that Bizkaia Gernika or Rovigo play well enough against Perpignan to deny them a try bonus point.
"It's not in our hands now. If Perpignan beat the other teams with a try bonus point then they will go through.
"We have just got to look after ourselves in our two remaining games, make sure we get the bonus point and do all we can do to get the maximum 10 points and see where we end up."
