The Germany international returned to action against Manchester City in midweek after a lengthy injury lay-off and admits he was delighted to be back playing
The 21-year-old had been out of action since picking up an ankle injury in the European Supercup win over Chelsea, but came on as a substitute in the midweek Champions League win over Manchester City.
Gotze has also been called up by Joachim Low for Germany's final two World Cup qualifying matches this month, but while he admits he is thrilled to be back, the former Borussia Dortmund man stresses he still has some way to go before he reaches full fitness.
"I still don't have the strength for 90 minutes. I've only been training for half the week. It was not so intensive," the €37 million man told Bild.
"I hope there will be more and more minutes. It's been nearly five months during which I've had no rhythm. I'm therefore delighted I can play again."
Gotze is in line to make his third Bundesliga appearance of the season at Bayer Leverkusen on Saturday.
