Napoli president Aurelio De Laurentiis lashed out on Sunday, claiming Juventus is given "preferential treatment" by Serie A referees after his side's 3-1 loss to the defending champion.

A pair of strikes from Paul Pogba and Arturo Vidal and Martin Caceres's first Serie A goal in over two years sent Juventus three points up on Roma atop the standings.

Juventus defender Giorgio Chiellini looked marginally offside when Andrea Pirlo whipped in a cross that Caceres converted in the 69th minute.
