The Slovak has been attracting interest from Manchester United and has previously also been linked with a move to Chelsea.
“If we rejected the rumours about a friend like (Carlo) Ancelotti and Chelsea it is obvious that we also reject these,” Bigon told Radio Marte when asked about United.
“We have no intention of giving away Marek.”
“It’s a normal thing that a player with the potential of Hamsik is followed with interest by big clubs,” Hamsik’s Italian representative Fulvio Marrucco told Napolipress.
“But I haven’t had direct contact with any English teams.
“Marek now only thinks of Napoli and the World Cup in South Africa.
“All the assumptions about the market are not true, there aren’t negotiations with any team and there isn’t the will of the player to change club.”
