The 21-year-old insists he has not quite reached full fitness yet following his injury, but is ready to play a full 90-minute match.
After Adrian Ramos scored the opener for the capital club, a double by Mario Mandzukic and a Gotze header ensured Pep Guardiola's men took all three points at the Allianz Arena.
And Gotze, who has recently recovered from an ankle injury, was delighted with contributing to the success despite acknowledging he has not yet reached full fitness.
"I'm at 95 percent of my potential and I think I'm ready to play 90 minutes again," the 21-year-old told reporters. "Playing 70 minutes was very important to me, I want to be at 100 percent again quickly. My goal was good for the team, especially towards the end. However, I was a little surprised myself how the ball ended up in the net."
The holding German champions currently top the Bundesliga table with a one-point lead over Borussia Dortmund.
