After resigning from Fiorentina, Gattuso held talks with Spurs before the Londoners abruptly ended negotiations.
Insigne remains close to the former Napoli coach and said: "We've texted each other, he told me there was a bit of mess.
“But now I am focused on the Euros, while he's on holiday so I am not going to ask him such questions."
Insigne says he expects to discuss new terms with Napoli after the Euros.
“I have no regrets, I've fulfilled my dreams to play for Napoli and be the captain of the team. I am more than happy. Now I am focused on the Euros and then I'll talk to the club,"
