Cristiano Ronaldo wasted no time in presenting himself to the Juventus faithful, scoring in his first appearance in the Bianconeri shirt after less than 10 minutes on the field.
The match is a traditional curtain-raiser in Turin, and gives potential first teamers the chance to test themselves against Juve's young hopefuls.
And Ronaldo certainly showed no signs of rustiness after his break as he opened the scoring for the first team just eight minutes into the game.
After latching on to Federico Bernadeschi's long pass, the forward found himself in blissful solitude in front of goal as he broke Primavera's offside trap.
He then converted in emphatic fashion, blasting the ball into the roof of the net to put his men 1-0 up.
He played a part in the second goal as well, putting Riccardo Capellini under pressure as a low cross came into the box and the Juve youngster put past his own goalkeeper.
Paulo Dybala then got himself a brace – his second a tap-in on the rebound after Loria failed to keep hold of Ronaldo's effort.
The 33-year-old was brought off at half-time, but not before one over-affectionate fan ran on to the pitch and locked him in a hug which required the help of two stewards to get out of.
Juve made it 5-0 early in the second half through Claudio Marchisio, before the traditional pitch invasion brought the game to a close in the 70th minute.
As well as Ronaldo, new signings Emre Can and the returning Leonardo Bonucci were present at Juventus Stadium for the warm-up match.
Ronaldo formed a front three alongside Dybala and Douglas Costa, a trident that will surely produce plenty more goals as the Serie A season gets underway.
