Defender Leonardo Bonucci described their performance against the Danish champions as "close to perfection" while goalkeeper Gianliugi Buffon said it showed that few teams could match the Serie A champions on a good day.
"We are Juve and we have to try to win every game we play," Bonucci told reporters.
"We played a very good game, this was a great Juventus. I think we were close to perfection."
Assistant coach Angelo Alessio, who is standing in for the suspended Antonio Conte, added: "Everybody played well and the result is clear: it was a great performance."
Buffon said: "This was a very convincing performance that showed if Juve step on to the field with the right ingredients then few teams in the world can keep up with them."
Juve's relief was certainly understandable given the circumstances.
Yet, just as talk of a crisis following Saturday's defeat may have been exaggerated, they appeared to be over-reacting to their win against inexperienced opponents who had already conceded seven goals in the group and scored only one.
Juventus attempted to bring Sergio Aguero to the club last year but, with UEFA's financial fair play looming and Serie A in financial difficulties, they have discarded any further attempts at big-name signings.
"I would say that is an almost utopian idea, not just for Juventus but for any of the Italian teams," said sporting director Giuseppe Marotta before Wednesday's game.
"I think it would be very unlikely for a club to invest more than 30 million euros for a player."
