This uneventful victory against the red lantern does not make us forget the humiliation on Wednesday against Villarreal (0-3) but maintains the beautiful dynamic of Turin in the league with a 16th consecutive meeting without defeat (11 wins, 5 draws).
It offers the opportunity for the "Old Lady" (4th) to climb on the podium on the next day (31st day), with the arrival of the Nerazzurri.
Dybala showed he had a sense of timing, quickly opening the scoring with a crossfire (5th) on the eve of resuming laborious negotiations for a possible extension.
The Argentinian, at the end of the contract in June, had missed a lot against the Spaniards, only entering at the end of the match after having missed several weeks due to injury (thigh and hip).
This time he played just under an hour and came out to a standing ovation from the Juventus Stadium.
Vlahovic, passer on the first goal, quickly protected Juve from any unpleasant surprises by doubling the lead (29th), to join Ciro Immobile at the top of the scorers' rankings (21 goals).
Other good news from the Turin afternoon: captain Giorgio Chiellini, absent since February 6 (calf), resumed service for half-time less than a week before the start of the qualifying play-offs for the World Cup-2022 waiting for Italy.
On the Salernitana side, Franck Ribéry also made his return for the last twenty minutes after missing the last two matches as a precaution for a slight head injury following a traffic accident.
The Frenchman did not change the direction of the match but participated in the best period of the Campania team, not far from saving the honor on a volley from Federico Bonazzoli diverted by Wojciech Szczesny (74th).
The 30th day continues in the evening with in particular the Roman derby between Roma and Lazio, in the fight for 5th place synonymous with qualification in the Europa League.
