Juve legend Nedved praised the performance of Antonio Conte's men and described the game as a "great test of character".
"We are very satisfied with how the team approached the match," said the former Czech Republic international.
"Fiorentina play a great style of football, they have a more than capable coach and a dangerous team. But today we really wanted the three points and played well to get them.
"It was a great test of character and everyone worked towards the same goal. In January, we had a slight dip in form but you can't be at the top of your game over the course of a whole season."
Juventus now face Celtic in the Champions League on Tuesday night.
