The Montenegrin came in for criticism in the wake of his side's Champions League humbling at the hands on Bayern Munich on Wednesday.
However, Vucinic has hit back at the suggestions that he does not have the right mentality to play for the Italian champions.
"It really annoys me to hear people say that I play without desire," Vucinic told Sky Sport Italia.
"I train every day with commitment and try to give 100% in each workout. We'll put in a typical Juventus performance on Monday [against Lazio], playing with the same desire displayed up until now."
