Napoli say their defeat to Fiorentina last night was influenced by Juventus' moaning about their victory on the weekend.
Napoli lost 1-0 and saw a goal from Roberto Sosa ruled out by the match officials. Afterwards, Napoli chief Pierpaolo Marino barked: "The goal that was cancelled was a good one.
"Unfortunately, after the game with Juve, Napoli have become a marked team. (Ezequiel) Lavezzi had to experience five fouls before something was done about it.
"Gava is a good referee, but he can make mistakes. Now I hope that the effect of Juve is over."
