"The old lady" had two straight victories in the Champions League before the match against Zenit away.
The first half lacked real goal chances - and there was no real crackling event.
However, the Swedish national team player Dejan Kulusevski jumped into the 58th minute of the match and saved the evening for his Juventus.
The Swede was replaced by Federico Bernadeschi and with three minutes left of regular playing time, Kulusevski was served a post by Mattia De Sciglio on which he got a forehead.
The ball went through the post into the goal.
The goal made the 21-year-old a great match hero, as the match ended 1-0 to the Italian big team.
Juventus now tops the Champions League group after three victories.
