The 2002 and 2005 Amlin Challenge Cup winners know that back-to-back bonus-point victories over Worcester and Biarritz would guarantee a place in the last-eight, while picking up maximum points in those two games would ensure that they return to the AJ Bell Stadium for the knockout stages regardless of the results in Pools 2, 3, 4 and 5.
With a one-point lead over Biarritz, they could even secure top spot in the pool as early as this weekend if a bonus point win over the Warriors is followed by an Oyonnax whitewash of Biarritz at the Stade Charles Mathon a day later.
"We can go a long way to finishing top of the group if we beat Worcester on Friday. Biarritz travel to Oyonnax and it's not the easiest place to go and win, as we know," Diamond told the Sale website.
"Biarritz are, however, much improved and it could all come down to our game in Biarritz a week on Saturday.
"One thing is for sure, we are going to give it everything we have got to finish as one of the top four qualifiers which earns us a lucrative quarter-final at the AJ Bell Stadium in April.
"We have players who are willing to give everything for the cause and that's all you can ask for."
Sale enter the European encounters in fine form, having won three of their last four games and picked up a losing bonus point in their solitary loss since the 16-10 defeat at Oyonnax on December 5.
They were 16-8 winners at Newcastle on Friday night and came within a single score of beating Leicester at Welford Road prior to that after London Irish were downed 15-3 before Christmas.
Their last game in continental competition saw them rack up a half century in the home leg of their tie with Oyonnax so they head back into Amlin Challenge Cup action in high spirits.
"Kingston Park is a very difficult place to come and that was a must win game for Newcastle, really. It was a really hard fought game but our second half performance was very good. We were dominant in defence and Newcastle didn't really look like scoring," added Diamond.
"We set ourselves a target over the festive period and we had two wins and a losing bonus point so we are happy with how Christmas and New Year panned out for us.
"Now we want to keep building on the momentum, starting with Worcester Warriors this Friday evening."
