Vidal doubled his personal tally just over 10 minutes later when he peeled off his man to collect Leonardo Bonucci's cross before taking a touch and placing his effort into the far corner.
Juventus restored their two-goal advantage shortly after the restart when Mirko Vucinic lost his marker to latch onto a Bonucci ball, controlling it and then stabbing home from close range.
Things got even harder for the visitors just past the hour mark when Hernanes handled inside the opposition box, prompting the referee to show him a second yellow card.
They were almost 4-1 down shortly afterwards when Carlos Tevez curled a shot against the crossbar after good link-up play with Vidal.
Tevez did get on the scoresheet with just under 10 minutes to go, finding space to shoot from the edge of the box and curling an effort past Federico Marchetti.
