Via ESPN, Messi's mother Celia Cuccittini gave a revealing interview about her son to the El Trece TV show "Diario de Mariana".
"His aim is to bring the Cup home, to win the World Cup". "It's one of his biggest desires".
"I don't know. It will depend how we do, how it ends", Messi told Catalan newspaper Sport before the tournament when asked if he will retire after this World Cup.
It was their world cup debut - against the mighty Argentina, no less - so Iceland fans all over the country were always going to be watching.
"We need to move on to the next phase, that's what we came here for", he said. "Obviously it hurts me to have missed the penalty", he said.
"But tell me: who helped him against Iceland?"
"I see him very relaxed and he has a lot of confidence".
BRONNITSY, RUSSIA - JUNE 19: Lionel Messi of Argentina arrives prior a training session at Stadium of Syroyezhkin sports school on June 19, 2018 in Bronnitsy, Russia.
"Messi does not have any substitute here, in Barcelona or anywhere in the world". Yes, we have lost three finals in recent years, but we reached three finals and that was a good achievement.
While Messi has proved himself time and again for a decade and more at club level, global glory has eluded the maestro who has had so many agonising brushes with glory in his pursuit of success with Argentina.
While we should take Ramos's quotes at face value, it's important to note what Maradona said about the Spanish central defender earlier in the week.
To add insult to injury, after Argentina's 2014 World Cup loss, the team then went on to lose in the finals at the Copa America in two straight years.
Indeed, there's a real chance that Argentina will fail to escape their group at this World Cup after being held to a 1-1 draw by Iceland in their opener.
Sampaoli also appealed to Argentines to stop arguing about whether Messi is better or worse than Maradona, who won the World Cup in 1986, and appreciate both men's contributions to their nation's sporting history.
