Napoli President Aurelio De Laurentiis has warned Real Madrid off making a bid for Edinson Cavani.
The 23-year-old Uruguay international striker has scored 27 goals in all competitions this season.
Reports in the Spanish media over the weekend suggested that Real Madrid are considering making an offer worth €50m for Cavani in the summer.
“The question shouldn't even be asked because the player is unsellable,” De Laurentiis said.
Asked to describe how he would react if Real Madrid did make such a big offer, he joked: “I would respond by blowing them a raspberry.”
As expected Napoli striker Ezequiel Lavezzi and Roma full-back Aleandro Rosi have received three-match bans for spitting at each other.
Both players were tried by television after the referee missed the incident during Saturday evening's clash at the Stadio Olimpico.
A yellow card had been given to Lavezzi and Rosi for the melee that followed.
Napoli's Ezequiel Lavezzi had a difficult weekend with his wife being robbed at gunpoint in Naples.
She is the latest in a string of people connected to Napoli to be robbed in recent years and fans now fear one of their top forwards could ask to leave having already courted moves away in the past.
"If this happens again we are off," she was quoted as saying by Monday's Gazzetta dello Sport.
