Emanuele Calaio may have played his last game for Napoli after accusing management of fining him for a missed spotkick.
Calaio missed a penalty against Reggina earlier this season and was hit with a £2,000 fine after the match.
The fine is officially for "breaking internal regulations" after a minor indiscretion during training, but the Palermo native claims it is an excuse to punish him.
"If I had scored, would they have fined me like that?" he inveighed bitterly.
