Napoli coach Walter Mazzarri admits he's a big fan of Juventus defender Giorgio Chiellini.

Chiellini has played as centre-back in a three-man defence, a four and as left-back in the competition despite struggling with thigh injuries.

"If I had to choose a player from this Italy squad to work with, it'd be Chiellini, as he is a lad who started out with me at Livorno.

"Giorgio is a force of nature, a universal player that any Coach would want in his team."
