Insigne departs for the MLS at the peak of his career.
De Laurentiis said: “He is a free man and therefore it is only right he makes the decisions that he finds to be correct to take care of his future.
“It is a long life nowadays, with a bit of good luck and some healthy eating, if he's got good genes, he could reach 110 years of age.
“So he might have 80 years ahead of him and has to think about that, it's only right he tries to take care of his future.
“This is nothing to feel guilty about."
