Juventus are on course to move six points clear at the top of Serie A after taking a 3-0 half-time lead against Parma in Turin.
Claudio Marchisio had the first chance for the hosts, but his low drive from the edge of the box was touched behind by Antonio Mirante.
Juventus made the breakthrough in the 24th minute when Paul Pogba's effort was parried by the keeper and Fernando Llorente pounced to slot home the rebound.
Stephan Lichtsteiner doubled the Bianconeri's lead five minutes later with a powerful drive from just outside the box that flew into the top corner.
The hosts were firmly in command and they grabbed a third soon after when Llorente was picked out by Lichtsteiner and guided an effort into the corner.
