The Buccaneers slipped to sixth spot in the DStv Premiership after being held to a goalless draw by the Durban-based outfit on Wednesday evening.
"Tough game, a lot of work but not the luck that we need, in the first-half a lot of playing close the box but the final ball was not correct, a lot of turnover overload on the side, overload inside the box but the final pass not correct," Zinnbauer told SuperSort TV after the match.
"The second-half both sides running, both teams looking for three points we tried we did not have the luck we need, we scored but offside, we also had a good situation to score a cross but it's always a step too late, then you get a draw. We wanted three points, it's not a discussion for us, the team works but we did not get the results that we want."
After a goalless first stanza, the German tactician made a double change on the hour-mark, bringing on Deon Hotto in place of Bongani Sam while Gabadinho Mhango came on for Thembinkosi Lorch.
"The subs Sam made a good game but a lot of time [not playing], he was a little bit tired and we changed, we got a bit of freshness, with Hotto more power upfront, the subs were okay but we didn't have the luck that we need," he said.
"I cannot say the team is not working but we did not have the luck to get the goal for a win. You have to play, work on it, it's coming, it's football. You try it, you have chances and you don't score.
"The opponent had the same problem, they had opportunities. You have opportunities and you don't score you cannot win," he added.
