Napoli president Aurelio De Laurentiis has confirmed that defender Kalidou Koulibaly will be fined by the club.
As reported on FastOneTwo.com on Thursday, the relationship between the player and the club has broken down after he spoke about his future with L'Equipe.
Chelsea are interested in bringing the Senegalese to Stamford Bridge but De Laurentiis has threatened to take legal action if he finds out that the Blues made direct contact with the 24-year-old.
"He went against what is written in his contract so I will fine him," De Laurentiis told La Repubblica.
"He also went against our agreement concerning rights to his name and image.
"Eighteen agreements were called off [because of what he said] so I am forced to take legal action against him for millions of Euro.
"[If he will leave?] Absolutely not. He has to work for us for three more years and for many more to repay us the damages.
"Contracts are respected here [at Napoli]. Koulibaly is 24, he's not a child. He struggled during his first season here but we defended him. Out of respect to Napoli and [coach Maurizio] Sarri he shouldn't have spoken like that.
"An apology is not enough.
"I never contacted a player before contacting his club [over a possible transfer]. If we find out that Chelsea [made contact], we might also take legal action against them"
