Pirates, who visit Kaizer Chiefs in the League on Saturday, will first host Abafana Bes'thende at Orlando Stadium, fresh off their 1-1 draw with Esperance, which set up a continental showdown with Al Ahly next month.
Mahamutsa scored the crucial away goal in Tunisia this past weekend. And while he is delighted with Bucs' progress in the CAF competition they previously won in 1995, he is wary of the Soweto outfit dropping their guard against Arrows in their quarter-final duel.
"We are determined to win the African Champions League and we are happy to have qualified for the Final. But for now we have a job to do locally – starting with the match against Golden Arrows and then the Derby," Mahamutsa told his club's official website.
"What is important for us right now is to maintain our momentum. Winning both matches will give the team the necessary confidence ahead of our first leg against Al Ahly."
He added: "The morale in the group is good at the moment, we look forward to the match against Arrows.
"Obviously it won’t be an easy match but I’m confident we will qualify to the semi-finals."
