It was the morning after the night before for Argentinian fans in Nizhny Novgorod on Friday and the recriminations from the devastating Croatia defeat just hours earlier were well underway.

The realisation that the 3-0 thumping by Croatia -- complete with comedy first goal -- had left the mighty two-time winners on the verge of a humiliating exit, left some of their fans in tears.

On Friday, many remained stunned by what had happened.

"We can't sleep, we can't talk, we can't do anything," said Sebastian, a 34-year-old lawyer who had travelled to Russia from Rosario.

"We've never seen anything like last night."

The team, he said, had shown no "huevos", using the Spanish slang for testicles.

Susi, a grandmother from Buenos Aires who spent an eye-watering $40,000 taking her son and grandson to Russia, said the result was so bad it could have implications for Argentina's president, Mauricio Macri, as he battles economic problems at home.

"If Argentina loses, it can become a social problem," she said.

The defeat was arguably the most shocking result of the tournament so far.

A team thought among the favourites for the World Cup, with superstar Lionel Messi as captain, were not expected to struggle through the first stage.

They certainly weren't expected to play so badly.

The result was Argentina's worst at a World Cup since being dismantled by Johan Cruyff's "Total Football" Dutch side 4-0 on a thundery night in West Germany back in 1974.

Nor were Argentina meant to rely on the results of Iceland or Nigeria just to remain in Russia.

With one point from two games, their fans were desperate for Nigeria to beat Iceland in Friday's game to retain hope of qualifying for the knockout stage.

"Today, all my country is Nigerian," joked Nicolas, 41, a company owner from Buenos Aires.

Fans of the "Albiceleste" could be spotted all around Nizhny on Friday.

Some were walking round town in kit, others with "Lio" shaved into their hair, and those draped in the country's flag, like Santiago, a student from the south of Argentina, as he prepared to head to Saint Petersburg for Argentina's crucial final Group D match on June 26.

Who was to blame? The embattled coach Jorge Sampaoli or the curiously listless players who have failed to produce, including the great Messi?

"I believe that the coach is not sure what he wants, or he is unable to pass this onto the players," said Santiago.

"But they also have to play, after all they are professionals."

- Down, but not out -

Despair though had turned to hope in the cold light of day, or at least the first signs that all was not lost

Cousins Juan and Valentino from Cordoba were about to embark on a 20-hour journey by train and plane via Moscow, Rome, Madrid and Buenos Aires to go home.

Their Russian odyssey was over but maybe not their team's.

Valentino complained that the Argentinian public and media put too much pressure on the side.

"The people think that the only way is to win the World Cup, they don't consider it a probability to lose," said Valentino, a 19-year-old student.

Juan called for as many as five changes in the team for the Nigeria game.

"We have a potential chance, it's time to support the team," said the 37-year-old accountant hopefully.

"We were in the same situation as we are now (when qualifying for the World Cup).

"We did it one time, so we can do it again."

Nigeria will take delight in ending potentially Lionel Messi's last World Cup for Argentina despite their love and admiration for the five-time world player of the year, promised Super Eagles coach Gernot Rohr.

Victory for the Africans in Saint Petersburg on Tuesday will send Argentina home in disgrace after failing to win a game in Russia and send Nigeria into the last 16.

"We love this great player, Messi, everybody loves him," said Rohr on Monday. "The question is not if it is the last World Cup for him or not, the question is for us to be qualified.

"We are not here to watch him playing. We are here to make a result, we are professionals.

"We are here to defend the colours of Nigeria and we know in football there is no mercy, no pity, everybody wants to win and we cannot make any gifts even if we like very much this player."

Messi carried Argentina through a troubled qualifying campaign but has so far failed to fire in Russia, missing a penalty in a 1-1 draw with Iceland before Croatia thrashed the two-time world champions 3-0.

Nigerian defender Brian Idowu admitted he would love Messi's shirt as a momento, but also insisted he wants to send Argentina packing.

"Our main goal is that it will be Messi's last World Cup game, as much as footballers we love watching him play," said Idowu, who was born in Saint Petersburg and still plays his club football in Russia for Amkar Perm.

"I would love of course to swap jerseys with him but I would love to swap jerseys with many players in the Argentinean side.

"They have many very good players and I watch them all play on TV, so it is not just Messi."

Nigeria moved into second place in Group D behind already qualified Croatia by beating Iceland 2-0 thanks to an Ahmed Musa double.

However, that victory came at a cost as captain John Obi Mikel suffered a fracture in his left hand that means he will be forced to wear a cast if he is to face Argentina.

"The captain has a fracture of the third metacarpal of the left hand. It's not so big fracture, it's a little one, but he has to play with a cast," added Rohr.

"We have to ask to the referee to accept, but it is hard plastic so I think it is ok. (He has) not so many pains and he will be ready I think."

France midfielder Paul Pogba said the finals in Russia might be his last World Cup but he hopes he will be fit for more.

"It might be my last World Cup," the Manchester United player, 25, told a news conference ahead of Tuesday's Group C final game against Denmark.

France have already qualified for the last 16 and will secure top spot if they avoid defeat.

"I'm realistic, we don't know if I'll be called up, maybe other players will be better than me," added Pogba.

"I hope I'll play more. I've already had the chance to play two, some can only dream to play one."

Dramatic late strikes by Philippe Coutinho and Neymar gave Brazil their first win of the World Cup against Costa Rica in St Petersburg on Friday and broke Central American hearts by sending them out of the tournament.

The result leaves the five-times world champions with four points from two games after they drew 1-1 with Switzerland in their opening match, and they provisionally rise above Serbia to top Group E.

Serbia play Switzerland later on Friday.

The clock had ticked past 90 minutes when Marcelo crossed from the left and substitute Roberto Firmino headed the ball back across goal to Gabriel Jesus.

Jesus's first touch took the ball away from the defender and Coutinho raced in to poke past Keylor Navas from six metres out and claim his second goal of the tournament.

Neymar added the second with practically the last kick of the game, racing on to Jesus's square ball following a quick counter-attack as Costa Rica were forced to push for the equaliser.

The forward, who thought he had won a penalty in the 77th minute only for the referee to reverse the decision after consultation with the video assistant referee (VAR), was overcome by emotion on the whistle, covering his face as tears streamed down his cheeks.

For long periods Costa Rica's flat-back five kept Neymar on the periphery, with Johan Venegas and Cristian Gamboa both man-marking him out of the game as Brazil found it hard to carve out chances in the first half.

Marcelo's tame shot straight at Navas in the 41st minute was the first effort on target from either side before the break, and the team went into halftime with the boos and whistles of their own fans ringing in their ears.

Celso Borges spurned arguably the best chance of the first period for Costa Rica when he ran on to Gamboa's cut back but shot wide from eight metres out.

The result means Brazil have avoided the ignominy of equalling their longest winless run at the World Cup.

Argentina and Nigeria will be battling it out for a last-16 spot of Group D in the World Cup at the Krestovsky Stadium in Saint Petersburg.

Argentina are currently enduring their longest winless run in a first-round World Cup group stage in history. Nigeria, on the other hand, has an advantage over Argentina in terms of points but has lacked consistently so far in the Group Stage. Nigeria are second in their group and could qualify should they beat Argentina. The South American side, however, still have a final shot at making it to the last 16 if they are to beat Nigeria, and if Croatia managed to avoid defeat to Iceland.

The match is scheduled to start at 12:00 am in Bangladesh time. Let’s look at some of the statistics ahead of the thrilling encounter.

     Head-to-head:

1. In each of the last four World Cups Nigeria have qualified for (2002, 2010, 2014 and 2018) they have been drawn in the same group as Argentina. They were also in the same group in 1994.
2. The Super Eagles have lost all four of their previous World Cup games against Argentina, with all of those defeats by single-goal margins (1-0 in 2002 and 2010, 2-1 in 1994, 3-2 in 2014).
3. The Nigerians lost a group game to Paraguay at the 1998 tournament, so have been defeated in all five of their World Cup matches versus South American opposition.

    Nigeria

1. Nigeria's six World Cup wins have all come against European sides - they have never beaten opposition from another continent.
2. The only previous time the Super Eagles won back-to-back World Cup games was in 1998, when they defeated Spain and Bulgaria in their first two matches.
3. Victory would ensure Nigeria reach the knock-out stage for a second successive World Cup, and for the fourth time in six appearances overall.
4. Ahmed Musa is Nigeria's all-time top scorer at the World Cup with four goals - two against Iceland at this tournament, and two versus Argentina in 2014.

   Argentina

1. The only previous time Argentina have failed to win a game at a World Cup was in 1934, when the tournament was a straight knock-out. They selected an inexperienced, amateur squad, and lost 3-2 to Sweden in the first round.
2. They have never completed a first round group stage at a World Cup without at least one win.
3.  The Argentines are enduring their longest winless run in World Cup history (D2, L2), although that four-match streak includes the 2014 semi-final against the Dutch, which they won on penalties.
4. They last lost back-to-back World Cup games in 1994 (against Bulgaria and Romania). They have never lost consecutive games in the opening group stage.
5. Lionel Messi has failed to score with his last 22 shots in matches at World Cup finals.
6. But over the last two years he has scored 14 goals in 18 games for Argentina.
