Sale first-team coach Tony Hanks said the 41-21 win over Agen was 'owed' to the fans after recent home results.
In their last game at Edgeley Park the Sharks lost 30-23 to Exeter after leading 23-7 at half-time.
"We owed the supporters, we owed our families, we owed ourselves a better home performance after Exeter," he told BBC Radio Manchester.
"We looked a lot more composed and from the coaches' box that gives you a lot more confidence."
The bonus-point five-try win leaves Sale second in Pool 5 of the European Challenge Cup, three points behind leaders Brive.
If the Sharks can win their remaining two group fixtures in convincing fashion they should progress as pool winners.
"We've taken 10 points out of the last two fixtures against a top-four French side," Hanks added.
"If someone had given us that at the beginning of the tournament we would have taken it.
"As long as we get the job done in Benidorm we'll be hopefully coming back here for a winner-takes-all game against Brive."
Hanks, who is in charge of the Sharks attack, game plan and defence, reserved special praise for winger Tom Brady who scored two of Sale's five tries.
The-Urmston born winger finished as the club's highest try scorer last season despite two serious shoulder injuries and has now crossed the line four times this year.
"For Tom Brady it's been tough at times," Hanks stated.
"That's probably been one of the positions that there has been the most competition in terms of the wing, but he took his chances.
"I've been critical of Tom at times in terms of finishing but he took his chances, I thought he carried really strongly, I thought he was busy and his work rate was good."
