Juventus have battled back from a goal down against Genoa to make it three wins out of three in Serie A.
The champions fell behind in the 18th minute when Ciro Immobile arrived late at the back post to slot past Gianluigi Buffon.
Luigi De Canio's men managed to hang on until half time, but were helpless to stop a relentless Bianconeri onslaught in the second 45 minutes.
Emanuele Giaccherini drew Juve back on level terms with a shot from distance, before Mario Sampirisi brought Kwahdo Asamoah down inside the area.
The referee pointed to the spot, and Mirko Vucinic stepped up to confidently sweep home the spot kick.
Asamoah then wrapped up the points with six minutes remaining by weaving his way into the box, firing past Sebastien Frey.
