Cristiano Ronaldo had his goal in the first half ruled out by VAR for offside as his Juventus side managed a slim 1-0 win away at Parma.
Giorgio Chiellini's 21st minute goal separated the sides and earned Juve maximum points up for grabs at the Ennio Tardini Stadium on Saturday night.
With new Juve manager Maurizio Sarri absent as he recovers from pneumonia, it was a good way to start the Serie A season.
In stoppage time, Brazilian midfielder Hernani, on a season-long loan from Zenit St Petersburg, drilled a low free-kick just wide from 25 yards which could have earned a share of the points.
But Juve managed to hold on for long and secured the three points at stake.
