Mazzola, who considered himself a solitary person led a secluded life, prioritising football above all. His entertainment consisted of a few games of bowls near his house. He used to write down everything, both in regard to his personal and professional life. He was very strict and meticulous and demanded the same treatment from others; this was the main reason for separation from his first wife, who was no longer willing to live with his firm discipline. He separated from his wife in autumn 1946 and remarried on 20 April 1949 to 19-year-old Giuseppina Cutrone. On 4 May 1949, just days after his second marriage, he died in the Superga air disaster, unfortunately, as he thought he would die because of war or misfortune.
