The former France international is adamant that other players will have to step up to the mark if the Albiceleste are to triumph in Brazil this summer
The Albiceleste No.10 scored the decisive goal in his country's tournament-opening 2-1 victory over Bosnia-Herzegovina before netting a dramatic late winner in their 1-0 defeat of Iran.
Henry, though, says Alessandro Sabella's men can ill afford to rely so heavily on their star attacker if they are to have any hope of lifting the World Cup.
"Messi doesn’t play all by himself, so let’s talk about Argentina," the New York Red Bulls striker said of his former Barcelona team-mate in an interview with Fifa.com.
"It's clear that if Argentina win, Messi will play well. But, at some point, the guys around him will have to help him out.
"Has Argentina's time come? They haven't won the World Cup in quite some time. So it's not really a 'Messi problem'.
"The team has to play as a unit, work hard, and only then will you see Messi performing at the top of his game – it's as simple as that."
While Messi has made plenty of headlines in Brazil so far, Henry has been impressed by numerous other players, including a Germany attacker whom the Frenchman believes does not get the credit he deserves.
"Thomas Muller doesn't get talked about as much as Luis Suarez, Robin van Persie and Luis Suarez, but he keeps finding a way to stick the ball in the net," the Arsenal icon enthused.
"If there's a loose ball or deflected shot, he's ready to pounce. Even when he's not trying to score, he scores."
