The Montenegro international, who has ended his five-year spell with the Fiorentina with a switch to the Etihad Stadium, but he has made only one Premier League appearance to date.
The 23-year-old had played for his national team, Montenegro in their 4-1 World Cup qualifying defeat to England last Friday.
“I arrived at City behind in my physical condition and so I have always been behind the shape of others,” he told Tuttosport. “Then I went to the national team and I got injured again, thus losing more time.
“Against England, I proved to be in good shape and now I just need to play regularly to find the best condition, I’m not worried.”
“In the end, however, I chose to go abroad and now I’m happy. I don’t regret the choice I made.”
