Goalkeeper Wojciech Szczesny preserved Juventus’ unbeaten start to the Serie A campaign as Fiorentina threatened to open their account in style.
The reigning champions, who lost both Douglas Costa and Miralem Pjanic to injury before the break, found themselves under the cosh at the Stadio Artemio Franchi, but their Poland international kept the home side at bay with a series of fine saves to ensure the game finished 0-0.
But ultimately, both sides had to make do with a point – for La Viola, a first of the season and for the visitors, a first draw after two wins.
Ronaldo saw two efforts blocked in quick succession as Maurizio Sarri’s men attempted to set out their stall early on, although it was the home side who went close with 16 minutes gone when striker Federico Chiesa fired just wide from distance.
However, it was Szczesny who was the busier of the two keepers, denying both Gaetano Catsrovilli and Chiesa before wide-man Dalbert headed just wide from Ribery’s cross with half-time looming.
Ronaldo called Dragowski into action with a 64th-minute strike from outside the penalty area, but Fiorentina continued to press and defender Nikola Milenkovic saw a 77th-minute header from Erick Pulgar’s cross saved.
