However, defence coach Peter Murchie says Warriors were in a patchy run of form before winning the URC title last year.
Warriors lost two of their last three games of the regulation season a year ago before getting it right when it mattered most to defeat Stormers, Munster and Bulls and claim the championship.
"We're not in the business of losing games and being happy about it," Murchie told BBC Scotland. "But in the last game against Leinster (a 17-5 defeat) we looked a lot more like ourselves, based on the amount of young players we had playing and how we fronted up.
"It was definitely a step forward in terms of performance. Last year, I wouldn't say we were exactly humming in the three or four games before this period, so it is about putting our best quality performance out this weekend."
Glasgow's play-off bid has been boosted by the return from injury of Lions' call-ups Scott Cummings, Huw Jones and Sione Tuipulotu in recent weeks.
Tuipulotu, who played the first half against Leinster, "didn't look rusty at all" added Murchie.
"Obviously players who have got experience of having done it before, international players who have played on the bigger stage, he's obviously got massive leadership qualities for us," he said.
"He did pretty well in his 40 minutes against a tough opposition. He didn't look rusty at all, so it's big to have someone of his quality back available for these games."
