Dybala's future is in doubt as the Argentina forward's contract expires at the end of the season and the 28-year-old has been linked with a move to Serie A rival Inter Milan.
He did not celebrate his opener in the victory at Allianz Stadium, instead glaring intensely towards the stands.
Asked if that was a signal to the club's directors over contract negotiations, Dybala dryly said: "I invited a friend and couldn't see him. There are many people up there watching and I couldn’t find him."
After being asked if he was telling the truth, Dybala responded: "I don't know, that's up to you. There have been a lot of stories, and many things happened that I prefer not to talk about."
The result stretched Juve's unbeaten streak to eight games – only Inter has a longer run (12) – while it moved level on points with fourth-placed Atalanta as it chases a UEFA Champions League qualification spot.
Since the start of November, Juve has gained 26 points in Serie A, more than any other side in this period, although Inter (25) and Atalanta (22) have played two fewer games.
Dybala was less than complementary about Juve's playing style, though, and said it needs to focus on working harder than its opponents during the closing months of the season.
"I think we played well. We must try to be more consistent after scoring goals, as too often we score and then start to defend more, become afraid of attacking, and we can't keep doing that," he added.
"We are Juventus, of course we are in the running for the Champions League spots and must try to win. We don't play good football; that is not our strength, so we need to focus on hunger and trying to run harder than anyone else."
Juve is next in action on Wednesday (AEDT) when it hosts Sampdoria in the Round of 16 of the Coppa Italia.
