Chiellini got Juve off mark as Ronaldo frustrated

New Juventus coach Maurizio Sarri was missing from the sidelines as he recovers from pneumonia which will also see him miss next weekend's game against Napoli in Turin.

But Portuguese superstar Cristiano Ronaldo drew a blank as he begins his second season in Italy with a goal ruled offside and several missed efforts.

Juventus' new-look side resembled last season's apart from returning Argentine forward Gonzalo Higuain, back from Chelsea, preferred up front alongside Ronaldo in place of Paulo Dybala.

Juventus's new Dutch defender Matthijs De Ligt remained on the bench with Welsh international Aaron Ramsey not in the group, while French midfielder Adrien Rabiot came on late in place of Sami Khedira.

Defender Chiellini made the difference early, connecting with an Alex Sandro cross off a corner to fire in after 21 minutes.

It was just the 27th goal in Chiellini's 14-year Juventus career.
