The Serbian winger made his home debut for Juventus in the 3-3 draw against Sampdoria on Sunday.
“I am satisfied with my performance,” he told the press.
“But I can still do better.
“I managed to set up some important moves, but I am only at 70 per cent of my ability.
“I think that in one or two games’ time I could be at the peak of my physical condition.
“I am not happy with my dribbling. I didn’t manage to beat my man like I know how to and like I must do. This is my speciality.”
