He explained on RTVS: "For Calzona, being in Naples is like a dream come true. Everything has been done to satisfy all parties. But it's something that the Federation took care of and had to give its ok.
"Tomorrow I will be in Naples for the match against Barcelona, but it was a trip that had already been planned for some time: when the draw took place I decided not to miss a super match, it wasn't a choice linked to the coach."
On his offer, Hamsik, who is Slovakia team manager, added: "Calzona contacted me when there was the possibility. He wants me with him. Tomorrow I will definitely see De Laurentiis in Naples, but I have already explained to both of them that I feel I have to stay in Slovakia and not in Naples. an attractive offer for me, Naples is my second home and one day I would like to return there. But this is not the right time."
