So Neymar wants to help Messi qualify for the World Cup by beating Chile.
Lionel Messi "still has to win a World Cup" to cement his greatness, but Federation Internationale de Football Association president Gianni Infantino expects to see him in Russia.
That's the bad news for the Albiceleste.
Brazil boss Tite is expected to play a very strong side against Chile.
In a qualifying process which has been in large part boring and predictable, the gruelling and mammoth race for progress in South America is a thrilling exception.
A win would see them go through, but a draw would give them a possible playoff spot.
With World Cup qualifying coming to a close, there is still everything to play for in South America with five teams battling over automatic qualification, as well as a play-off spot.
Chile were under Argentine-born former Spain striker Juan Antonio Pizzi when they stunned Argentina again a year later in the final of the Centenary Copa America in the United States, also on penalties after another 0-0 draw. Only Brazil has so far qualified, with Uruguay, Chile, Colombia and Peru all ahead of Argentina.
Ecuador vs Argentina is available in most nations through the rights holders' online platform, if they have one.
October 11 at 02:30 in Quito at the stadium "Atahualpa Olympic Stadium" Ecuador will take the national team of Argentina in the match final round selection for Mundialyu. A draw would likely put them in unless Chile gets a point from Brazil and Argentina and Paraguay both win, with the latter making up a significant amount of goal differential.
And so it all comes down to Tuesday night's game in Ecuador, which has always been extremely hostile terrain for visiting teams for one simple reason: altitude. It's going to be a nervous 90 minutes for him.
Ecuador won 2-0 the last time the sides met earlier in qualification, in Argentina, and the last time tonight's visitors won in Ecuador was in 2001!
In a worst-case scenario, Uruguay could lose to Bolivia and have Chile beat Brazil, Argentina beat Ecuador and have a victor in the Colombia-Peru matchup.
"The only ones who would be happy if Messi doesn't go to the World Cup would be Maradona fans because, that way, they can keep saying that he's the best", the 63-year-old added.
The good news for Argentina is that Messi is expected to play on Tuesday.
"I don't think he qualifies as the greatest that's ever played without winning the game's greatest prize".
