The Albiceleste head to next summer's World Cup in Russia preparing for what is likely to be the swansong for a number of their players.
Romero, Javier Mascherano, Angel Di Maria, Sergio Aguero and Messi are all at an age where they are unlikely to play again in 2022.
The latter is by far the most important and his impact during qualifying, most notably his hat-trick in their decisive final game in Ecuador, has led the likes of Mario Kempes and Diego Maradona to question their reliance on him.
The Manchester United goalkeeper is unrepentant though, insisting that it is impossible not to build a team around someone so talented.
He told TyC Sports: "We are going to be Messi-dependent all of our lives because he is the best and we know that at any time he can win us a game.
"It was clear and evident that without him [when Messi was suspended or injured in qualifying], we struggled. Perhaps we haven't been able to put all the pieces together as we should have.
"I don't mind they criticise us for playing badly. We accept it."
