Thanks for joining us this evening, be sure to check back for a full match report, player ratings and reaction from both camps. Enjoy the rest of your night!
FT: The referee signals for full-time and Argentina are 3-2 winners in Porto Alegre. A Lionel Messi double in the first half and Marcos Roja's effort from close-range have sealed top spot in Group F for Alejandro Sabella's men, but Nigeria, who twice hit back through Ahmed Musa, will also be joining them in the last-16. 2-3.
Di Maria spots Enyeama off his line and goes for goal, but the referee has already pulled play back for a foul.
We're into the first of four minute's added time in Porto Alegre as Nigeria search for an equaliser. Argentina are hoping the introduction of Biglia will help shore things up in the middle.
Enyeama shows safe hands as he clutches Mascherano's ambitious strike from range. Argentina look to be preparing a final change.
NIgeria are pushing forward but Emenike is unable to bring the ball down inside the area as Rojo clears the danger momentarily. Ambrose then takes over and his strike cannons off Garay and into the side netting.
CHANCE! Emenike tries his luck from range as he hooks an effort just wide of Romero's post with the Argentina goalkeeper scrambling for it.
Musa hits a teasing cross towards the back post but Nwofor is unable to reach it as the ball bounces harmlessly behind for a goalkick.
Emenike drills a low cross into the six-yard box. It initially evades everyone before Mascherano casually strolls away with it.
Fernandez is unconvincing in his clearance as his outstretched leg slices Mikel's cross behind for a corner.
CHANCE! Di Maria whips an inviting cross towards the back post and Garay, who loses his marker, powers a header just wide of Enyeama's goal.
Musa, on a hat-trick, is found by Emenike inside the area and he cuts inside before unleashing a strike on goal, only for a brilliant block from Zabaleta to deny him.
CHANCE! A well-worked free-kick routine between Di Maria and Lavezzi sees the latter go through on goal and force Enyeama into a smart save to push it behind for a corner.
Odemwingie is afforded a bit of time on the edge of the Argentina box and he tries an audacious chip with few other options available, but he is only able to find the arms of Romero.
Musa nods the ball down towards Onazi who whips a first-time cross into the area where Emenike is waiting. Garay reads the game well and hacks it clear.
CHANCE! Musa blasts a first-time effort well over the bar after the ball found him on the edge of the area. Pressure from Mascherano meant he had to get that one away quickly.
Odemwingie wins a corner off the heels of Rojo and Nigeria send men forward from defence. Odemwingie takes the set-piece but his delivery is poor and Argentina clear.
Lavezzi accelerates towards the byline before whipping a ball across goal. It beats everyone, though, and Nigeria are able to clear.
Enyeama is composed on the ball to bring a heavy backpass under control and feeds Yobo. Nigeria come forward but Mikel finds his path blocked off by Mascherano.
Emenike is hurt after going to ground under a strong challenge from Mascherano. He looks okay to continue though as Romero restarts play from the back.
Lavezzi and Alvarez try to work an opening following a short Argentina corner, but their casual approach does them no favours as Nigeria are able to clear up-field.
Higuain holds up play well and spots the run of Di Maria out on the left as Argentina break, only for Yobo to step in and snatch it off him.
Enyeama rushes off his line to gather the loose ball with Alvarez in close pursuit. Both Keshi and Sabella are issuing instructions from the sidelines.
Babatunde leaves the field on a stretcher with his arm strapped up as Michael Uchebo replaces him for Nigeria.
We have a stoppage in play as Babatunde is down and receiving treatment inside the Argentina half. There seems to be a bit of concern about him after Onazi's strike slammed into his arm.
Messi leaves the field to a wonderful ovation as he is replaced by Ricky Alvarez for Argentina. No hat-trick today but you can't blame Sabella for wanting to rest Messi for the knock-out stages.
CHANCE! Mikel finds the ball at his feet at the back post with a clear sight of goal. He looks to get a shot away but can only find the arms of Romero with a weak effort.
Oshaniwa powers beyond Fernandez before sitting a cross up towards the back post. Nobody in a green shirt is able to meet it before Musa takes over and wins a corner.
CHANCE! Messi directs Rojo's low cross just wide, but he was always stretching back to reach the delivery. He wants a corner but the goalkick is given.
The midfield is rather congested as Gago is unable to find a way through. Bosnia have made it 2-0 against Iran which should be enough for Nigeria no matter what happens here.
Omeruo tangles with Higuain before conceding a corner which Messi will deliver. The Argentina fans are in great voice.
Messi is tugged back by Onazi and Argentina have a free-kick inside the centre circle. Nigeria are starting to frustrate them now as they push for a fourth.
CHANCE! Messi dances forward before poking Higuain through on goal. Enyeama, who has been outstanding for Nigeria, rushes off his line to smother at the Napoli striker's feet and guide it behind for a goalkick.
Enyeama palms away Di Maria's strike across goal after Lavezzi had burst into the area. What a game we have on our hands here.
GOAL! Argentina retake the lead as Rojo gets the slightest of touches on Garay's flick-on to knock it beyond Enyeama! 3-2!
CHANCE! The loose ball falls to Di Maria on the edge of the area and Enyeama reacts well to tip it behind for a corner.
That's two for Musa now and another good finish. Argentina won't be best pleased with their defending there though as the Nigeria man was allowed to ghost right between the two centre backs.
Ambrose and Odemwingie try to force an opening down the right but Argentina have men back in numbers and Rojo muscles in to come away with the ball.
HT: The referee signals for half-time and Argentina lead 2-1 thanks to a double from Lionel Messi. He fired them ahead from close range after just three minutes, but Nigeria immediately hit back through Ahmed Musa. Messi has been on top form, though, and his beautiful free-kick just before the break is the difference. 1-2.
Messi strides forward once again before being hacked down by Omeruo for another free-kick in a dangerous position.
CHANCE! Messi goes for goal with an outrageous free-kick from range. It looks to be sailing into the top corner but Enyeama does well to fly across his line and push it away for a corner.
Mikel is pulled up after tussling with Lavezzi and Argentina have a free-kick in a decent position for a cross. Messi stands over it and will deliver, left-footed.
Lavezzi hits a low cross into the area but no-one in a blue and white shirt is able to meet it before Ambrose puts in a strong challenge to deny Di Maria from bursting into a crossing position.
Higuain is unable to find away past Mikel and Nigeria break. Musa is can't keep the ball in play though and Argentina have a goalkick.

Babatunde eventually gets the free-kick in but play is halted for a Nigeria foul as the ball was delivered.
There's a delay taking the free-kick though as Sergio Aguero is down inside the area and looks resigned to coming off with injury here as the stretcher is brought on.
Nigeria break and win a free-kick in a promising position as Emenike is bundled to the ground by Mascherano. Chance to get a delivery into the box here.
Argentina have seen 63 per cent of possession after just a third of the game. Nigeria have caused them problems in these early stages though and they continue to defend well.
Enyeama comes off his line to confidently pluck Messi's corner from the air, but the Nigeria keeper has injured himself after a collision with Higuain.
Argentina win a corner after Oshaniwa stood firm to deflect Aguero's powerful string behind following a surging run down the right from Zabaleta.
Di Maria pulls his weight defensively as he gets back to bring the ball forward before winning an Argentina throw.
Argentina play the corner short before Di Maria whips a cross towards the back post where Rojo has made a run to glance the ball well wide under pressure from Yobo.
CHANCE! Di Maria is invited to strike from distance and he unleashes an ambitious low effort. Enyeama is equal to it, though, as he gets down well to tip it behind for a corner.
Messi holds off the challenge of Odemwingie and continues to stride forward, but his final ball is wasteful as it goes out for a goalkick with Higuain not quite on the same wave-length.
CHANCE! Odemwingie fancies his chances from range as he lets fly with a powerful left-footed strike which sails just over Romero's bar.
Garay is forced to be strong under pressure from Emenike as he ushers the ball behind for a goalkick.
CHANCE! Argentina work an opening after some smart one-touch football involving Messi and Higuain. The ball finds its way to Di Maria arriving at the back post and he drags an effort well wide.
Bosnia have taken the lead in their game against Iran which means that as things stand, Nigeria will be heading through to the last-16 regardless of the result here.
Emenike has looked a handful so far but he is just unable to bring Babatunde's ball over the top under control as it goes behind for a goalkick.
Oshaniwa looks for the run of Emenike who brushes Rojo aside before Mascherano is well placed to cut out his low cross. Nigeria continue to press though.
Messi whips the free-kick towards the penalty spot and Mikel is relieved to see his flying header sail straight into the arms of Enyeama.
Messi draws a free-kick from a clumsy Oshaniwa challenge and Argentina have the chance to get a ball into the area. Messi stands over it.
Emenike is furious with the referee after feeling that Pablo Zabaleta had pulled him back. Nothing is given and Argentina have a throw-in just before the halfway line.
Nigeria continue to sit back with 10 men behind the ball as Argentina patiently probe for an opening. Omeruo intercepts the ball but Sabella's side will go again.
Rojo is found in space but again is forced to go back as Di Maria takes over. Messi comes from deep to collect before playing in Aguero, but Nigeria have men back in numbers again to clear their lines.
Enyeama is forced into action as he gets down low to gather Higuain's cross after some clever interplay from Messi on the edge of the area.
Ambrose is forced to hook the ball to safety after Higuain lofted a smart ball over the top for the run of Di Maria. Nigeria are doing well to stand firm against these waves of Argentina pressure.
Ambrose guides the ball back into the arms of Enyeama after Di Maria had looked for a way through. Nigeria get the chance to mount a rare attack through Babatunde but the move breaks down.
Messi feeds Di Maria before Argentina are forced to come back inside and start again from defence. Nigeria are defending deep with every green shirt inside their own half.
Emenike is just unable to reach it as Romero comes off his line to smother the loose ball after a brief Nigeria break.
Argentina play a free-kick short inside the Nigeria half before Yobo is forced to cut out a long ball over the top with Higuain lurking.
CHANCE! First Di Maria stings the palms of Enyeama with a strike from range before Messi threads Higuain through on goal. He tries to round the keeper but has taken it slightly too wide and is only able to find the side netting.
Neither Zabaleta or Di Maria are able to force an opening as they find themselves outnumbered by Nigeria. Emenike gives away a free-kick for pulling back Rojo and Argentina have a free-kick.
Wow. Absolutely breathless few minutes that pretty much sum up this tournament so far. Babatunde picked out Musa on the left and there was only one thing on his mind as he skipped away from Zabaleta before bending into the far corner.
GOAL! Nigeria hit back almost immediately as Ahmed Musa cuts inside before curling a superb effort beyond Romero! 1-1!
What a start for Argentina as Messi makes it three goals from three games this tournament. Mascherano found Di Maria in space with a great ball and he drove inside the area before smashing an effort against the post. There was a slight hint of fortune as it came back off Enyeama, but nothing fortunate about the finish as Messi hammered the rebound into the roof of the net.
There is a huge Argentine following inside the Estadio Beira-Rio, but Nigeria have started brightly as Odemwingie is found in space out on the right. He tries to cut inside but finds his path blocked by Mascherano, who hurts himself in the process.
Here we go then... National anthems and the usual pre-match pleasantries done, Argentina get us underway in Porto Alegre!
This is the fourth meeting between the two sides and history favours Argentina as they have won the last three. They are the favourites again this evening, but are likely to face a stern test against a Nigeria side looking to reach the last 16 for the first time since 1998. Their narrow 1-0 win over Bosnia was the first time they had won a World Cup game in their previous 10 attempts.
If you fancy a flutter on tonight's action, our friends over at Sky Bet have it covered with a number of Price Boosts on offer. Angel Di Maria to open the scoring is 10/1, but Nigeria to snatch a 1-0 win pays 22/1. Stephen Keshi's men are the underdogs tonight at 7/1, the draw is 100/30 while Argentina are 4/9 to claim three points.
Stephen Keshi's men opened their campaign with an underwhelming 0-0 draw to Iran, but Peter Odemwingie's strike was enough to see off Bosnia and they are now 90 minutes away from progression to the last-16.
Argentina have won their opening two games in Brazil - beating Bosnia and Iran - but they are yet to truly convince. A piece of genius from Messi saw them snatch a 1-0 win against Iran in stoppage time on Tuesday night, while he was also on the scoresheet for the 2-1 win over Bosnia in their opening game.
Chris Green from Huddersfield is the first to get in touch with his score prediction this afternoon. He says: "Argentina to win 3-0, with Messi (2) and Higuain scoring the goals."
So there are the teams and both sides are unchanged from their previous 1-0 wins over Bosnia and Iran respectively. But what do you reckon? Feel free to get in touch with your thoughts and score predictions throughout by either Tweeting me: @ryanparrish1919 or emailing email@example.com and I'll get them posted as we build up to kick-off.
Argetina team: Romero; Zabaleta, Garay, Fernandez, Rojo; Mascherano, Gago, Di Maria; Messi, Aguero, Higuain.
Nigeria team: Enyeama; Omeruo, Yobo, Ambrose, Oshaniwa; Mikel, Onazi; Babatunde, Musa, Odemwingie; Emenike.
