Fiorentina held Juventus to a 0-0 draw in Serie A on Saturday at the Stadio Artemio Franchi.
The hosts dominated the first half but failed to find a way past Wojciech Szczesny.
There was nothing to separate the two sides in the second half, either, with the Florentine side earning their first point of the season.
Ronaldo had an early sight of goal with a free-kick, but he failed to trouble the hosts with his effort, as GianlucaDiMarzio.com's David Amoyal observed:
David AmoyalRonaldo is going to need Mexico to pay for it if he wants to get past the wall on free kicks in Serie A- feels we’ve seen this so many times
Apart from a save Bartlomiej Dragowski made from Blaise Matuidi, Juve had little else to shout about in the first half as the hosts put in a fine showing.
