The Argentine will go down in history as one of, if not, the best player of all time.
You will be hard-pressed to find a football fan who has a bad thing to say about Messi.
But it appears there is one person who is brave enough to speak up whenever the superstar does have an off day.
Messi revealed that his kid Thiago is more than happy to ask questions whenever Barcelona slip up.
And he makes sure his dad now openly talks about those performances to reflect and improve for the next game.
