Pirates will visit Gaborone National Stadium on Sunday to face Jwanenge Galaxy in the first leg of their final Confederation Cup preliminary round fixture.
With a spot in the group stages up for grabs, The Buccaneers will be hoping to make it to the round-robin phase of the competition for the second time in their history after going on to finish runners-up back in 2015.
Zinnbauer, who is in his first foray into African inter-club football, has highlighted what their main focus will be in the upcoming away-leg, before they welcome the Botswana outfit to Orlando Stadium next weekend.
"The important thing for us is that we have a good result first in the away game. If we score, an away goal is good for us then maybe we make a draw or score more," Zinnbauer told the club's media.
"If we win, we have a top chance [to progress] at home, but first for us it is important not to concede - we don't get a goal in our goal. That's important for an away game.
"Then we have a home game and we can then correct the result, but we have a good mood and spirit now. The team is ready for the next step.
"They know what could happen when we win these two games – we then have a top chance for the next few [group matches] in the future, and that's important for us."
