His comments come after the recent spate of criticism that have been heaped over Argentina after their failing to inspire in their opening two Copa America games. However the side managed to crush Costa Rica 3-0 in their final group match largely due to some inspired performance from Messi.
The diminutive Argentine said, "I've never been bothered by what they say in the press and I never will be. I don't think anyone likes it when they're whistled and insulted. We're the first ones who want to do things well."
He added, "It's a mistake to compare this team to Barcelona. We've all been working together at Barcelona for a long time."
Further elaborating his views, Messi said, "In the national team we're trying to do something similar, keeping hold of the ball, dictating the rhythm of the game, but you can't compare the two teams, either as a group or in terms of individuals."
He added, "Argentina need a trophy. It's a long time since we've won one."
Argentina are banking on Messi, to give them their first major victory since their Copa America title triumph, way back in 1993. They will now take on Uruguay in the quarterfinals on Jul 16.
