Messi says he now "dreams" of becoming a father.
"I dream of being a father," he told Argentine magazine Caras.
"In football, you are faced with many questions and can easily become unsettled. Having the support of my family made everything easier," he continued.
"My family were always near me and often said [family support] was essential and very important for my career, especially towards achieving my goals, which is most difficult. You can get many doubts and become disrupted by everything that happens."
