Ilkay Gundogan says he intends to take his return to the Premier League slowly, hoping to be back by September.
The attacking midfielder scored five goals in 16 appearances last season , before sustaining an injury in December.
Gundogan came on in the final 19 minutes of the friendly match against Girona, which City lost 1-0.
“I’m in a good way. I still know that it’s a long way to go but I was out for eight months,” Gundogan told City TV
“There is no reason to rush now. When I feel good, when I feel ready, when I feel safe I’m ready to play and I’m ready to try.
“That’s the target for the next weeks. There’s an international break in the next two weeks so there’s plenty of time to use that for training, maybe another one or two games if it’s possible.
“Then, hopefully, after that break I will be ready to join the team fully. When the manager and my team-mates need me, I want to be there.”
