The Montenegro international believes their upcoming Champions League game with Chelsea could prove to be a defining moment in the Italian champions' season
The Montenegrin played a key role in the Turin side's run to the Serie A title last season, scoring nine goals and providing 12 assists, and although the former Roma man has not been quite as prolific in the opening months of this campaign, the Italian giants sit in a good position to retain their league crown.
However, while Antonio Conte's men are four points clear of their nearest challengers Inter Milan in domestic competition, they have work to do if they are to qualify for the knock-out stage of the Champions League.
Indeed, Juventus sit third in Group E, one point behind both Chelsea and Shakhtar Donetsk, and will need to take points against both of their qualification rivals if they are to have any chance of progressing.
Chelsea visit Juventus Stadium next Tuesday, and Vucinic believes that the outcome of that contest could well be key in deciding how successful their season will be.
He told the club's official website: "Lazio, Chelsea and AC Milan. These are three games that will decide the fate of our season, both in the league and the Champions League.
"We cannot afford any mishaps, especially against Chelsea, because we want to continue the dream and above all to keep winning."
