Maurizio Sarri's troops cemented top spot in the Italian top-flight with a 3-0 triumph over Fiornetina on Sunday afternoon in Turin.
Fiorentina president Rocco Commisso was upset that the Old Lady were awarded two penalties, which Cristiano Ronaldo converted.
"I've been here for six months, I've never criticised the referees, but I say now that referees cannot decide the games," he told DAZN.
"I am disgusted. Maybe the first was a penalty, but the second certainly was not. The referees cannot decide the games, they need to let the players do their work on the pitch.
Nedved, meanwhile, was not too pleased with the criticism aimed at Juventus and felt his side deservedly got the win over Viola.
"He's got all my respect but we're tired of this trend. Juventus have won with merit," he added.
"Enough with the excuses of those teams who lose against Juventus. We deservedly won today by doing a little more than them. Things should not be said before people have calmed down.
"This excuse is being used a little too much against Juventus."
