Lionel Messi on retirement talk: 'If I feel good, I will always try to continue competing'
"I am very self-critical. I know when I am good, when I am bad, when I play well, when I play badly ... And when I feel it is time to take that step, I will take it without thinking about age. If I feel good, I will always try to continue competing, because it is what I like and what I know how to do."
