Gotze is currently one of the hottest properties in European football after helping the club to back-to-back Bundesliga victories in the last two seasons.
While he struggled with injuries last term, the Germany international has been in fine form so far this campaign, even though Dortmund haven't exactly hit top gear yet, which is something Zorc had expected from his young star.
"I said before the season started that we would see the best of Mario," he told Bild. "It was just a matter of time.
"It is up to the coach where he plays, but Mario has the good fortune that he is as good in any position. He can play on the right, left, or play through the middle."
The 50-year-old, who used to play for BVB, also admitted the club face a tough route to the knockout round of the UEFA Champions League, after being drawn alongside Real Madrid, Manchester City and Ajax.
"We are German champions, so of course we want to make it through," Zorc added. "But it doesn't help now that we have Real Madrid and Manchester City.
"We need to make a good start and beat Ajax at home."
The Dortmund chief also maintained he was happy with the current squad, despite the summer departure of Shinji Kagawa to Manchester United.
"I am absolutely happy with our squad," he insisted. "When I see Rafael van der Vaart and Ibrahim Afellay join Schalke, I am of course a bit jealous.
"But we have attacking midfielders, and we saw no need to add to the squad."
BVB are back in Bundesliga action on Saturday when they entertain Bayer Leverkusen.
