Arrigo Sacchi was critical of Napoli's tactics for defeat at Juventus.

Sacchi felt Juve's self-belief was the key to Saturday's win.

“The team that believed in itself the most scored and therefore won," he told Mediaset Premium.

“The side with the most experience and the most strength in depth came out on top.

“All the strikers had negative performances because the teams did not give them the right level of support. Higuain was abandoned to his own devices up there, although admittedly he didn't move enough either.

“Napoli needed something remarkable to get the victory in Turin, whereas Juve only required a normal performance."
