Napoli sports director Pierpaolo Marino was delighted with Emanuele Calaio's brace against Livorno on Sunday.

"I want to publicly thank Roberto Sosa and Calaio who played a part in the club's history by helping us from Serie C to the top flight," he declared.

"As a club we want to keep hold of Calaio and didn't want him to leave in January as we have faith in him. Sosa-Calaio isn't a Third Division partnership and they showed that."
