"I was better [against Juventus] than in the first game", he told Madrid's TV station.
The five-time Ballon d'Or victor had been given a bit of extra time off to recover after his World Cup campaign with Portugal.
There should be more fans at the match than the entire population of Villar Perosa, with the 5,000 tickets available long-since sold out and even more supporters desperate to try and catch a glimpse of their new idol. And now according to Italian publications Tuttosport, the Brazilian left-back is keen on a move to Allianz Stadium.
"Having Ronaldo here will at least mean that if we meet Real Madrid we won't be starting the match already 1-0 down", said Bonucci, who has returned to Juventus after a year with AC Milan, at his official presentation in Turin.
Relations between Ronaldo and Florentino Perez had been cold for many months leading up to his exit, but there now seems to be warmth on either side with the European champions determined to honour one of their all-time greats.
His domestic form - despite scoring 26 goals in La Liga - was below the nearly superhuman levels that had characterised his time in Spain as Madrid finished third behind local rivals Atletico and a whole 17 points behind champions Barcelona.
Cristiano Ronaldo's desire to find a new challenge in his illustrious career was met with surprise in the Spanish capital, however, after nine seasons of incredible service he was allowed to depart for Juventus.
Marcelo saw former team-mate Ronaldo complete a move to Turin earlier this summer and interest from Juve could see the duo reunited.
