Even a win may not be enough for Argentina, who are bottom of the group - behind Croatia (six points), Nigeria (three) and Iceland (one).
Messi has come under fire in Russian Federation, where Argentina are in danger of making a group-stage exit after drawing with Iceland and losing 3-0 to Croatia.
Chances of advancing based on FiveThirtyEight's SPI ratings.
Speaking ahead of their final Group D game on Tuesday, Mascherano has stated that Messi is desperate to show the world the real Argentina.
"From outside it is hard to judge his exclusion from the World Cup", Verón told RMC Sport.
He told Paddy Power: "To see Messi walking with his head down, he should be ashamed". Only he knows. I hope he can drag the team and the team can accompany him. I don't think [past problems] are technical, because they're world champions at U17 and U20.
Sebastian Veron has questioned why Mauro Icardi was left out of World Cup squad. He's no Ronaldo in that regard.
"He is a human being who has his frustrations because things haven't worked out, but so are we all". He's not there anymore.
"It would be a shame to see them qualify, because against Iceland they looked awful, with no inspiration, nothing at all".
"He's not running, he's walking".
"The whole team's body language was so poor, no confidence, no trust between each other".
There have been reports that the squad led a revolt against manager Jorge Sampaoli and senior players will select the team against Nigeria.
"From outside it is hard to judge his exclusion from the World Cup". So if Iceland win by 1-0, then Argentina's scoreline has to be 2-0 or more and similarly, if they record a win by 2-0, Messi's team has to defeat Nigeria 3-0.
