Having endured a disappointing spell in the European competition, the Turin giants beat FC Copenhagen 3-1 on Wednesday for their first success in Group B.
The result in Turin left Juve second in the pool and needing just a draw from their final group game at Galatasaray to progress to the knockout round of Europe's elite club competition.
"This is a very important win for us," Juventus coach Antonio Conte said to Gazzetta dello Sport.
"We will go to Turkey to face Galatasaray knowing that destiny is in our hands.
"We will not make calculations but rather go there determined to take three points."
