Hello and welcome to our coverage of this FIFA World Cup Group C clash between Argentina and Mexico. It's a vital game for Lionel Messi's Albiceleste as they will be eliminated from the tournament if they lose today.
Italy's Daniele Orsato is the referee tonight.
Off we go! The match is underway. The stadium is absolutely rocking, as one would expect given the circumstances and the quality of players on show.
Argentina have come out of the blocks fired up, with Mexico remaining compact in the early minutes.
Mexico are growing into the game and giving as good as they've got. Lozano draws a foul. This looks like it's going to be a feisty encounter.
There hasn't been much for either goalkeeper to do in the opening minutes even though the challenges have been flying.
Guardado collides with Lautaro Martinez and the decision from Daniele Orsato goes Mexico's way, much to the chagrin of the Inter Milan striker.
Guardado goes short from a Mexico free-kick and they work the cross in eventually, but Emiliano Martinez is alert to the danger and holds on.
Araujo picks up a yellow card for a reckless challenge on Acuna.
Mexico attack down the right and Alvarez looks to get the cross in, but it goes behind for a goal-kick.
Argentina have really struggled to penetrate the Mexican defence so far. They need to be more innovative.
Messi's corner from the left is headed away only as far as de Paul, who wins a foul on Argentina's right flank off Vega.
Messi's inswinging free-kick proves problematic for Ochoa, whose punch goes straight upwards. However, he wins the foul as the ball descends.
Lisandro Martinez is receiving medical attention after receiving a boot to the face.
De Paul looks to make headway down Argentina's right again, but overruns the ball. Goal-kick to Mexico.
Gutierrez is on in place of Guardado in an early Mexico substitution.
Di Maria's inviting cross from the right finds Martinez, whose glancing header misses the target. That's better from Argentina.
Montiel picks up a yellow card for catching Gutierrez late.
HALF-TIME: ARGENTINA 0-0 MEXICO. It's been a cagey encounter so far. Lionel Messi was the name on everyone's lips in the build-up, but he's been largely anonymous tonight. Argentina are clearly far from the finished article.
Vega lets fly from long range, but can't hit the target.
We're into five minutes minimum of additional time at the end of the first half.
Vega goes for goal from the ensuing free-kick but Martinez reads it superbly and makes a diving catch.
Off we go! The second half is underway.
Lozano tries his luck from long range, but the shot is blocked by Rodriguez.
Messi goes on a trademark marauding run after a one-two off Mac Allister and wins a free-kick off Gutierrez, who had to get him down by any means and picks up a yellow card. Messi will likely want to try his luck here.
Messi dinks the free-kick over the wall, but doesn't get enough dip on his free-kick to trouble Ochoa.
Di Maria drives down the right and gets the ball into the danger area, but Mac Allister can't get a shot on target as he's surrounded by bodies in Green and white.
Argentina are seeing plenty of the ball, but they need to work Ochoa far more in this must-win game for them.
Montiel and Lautaro Martinez make way for Argentina with Molina and Alvarez on in their place.
GOAL, ARGENTINA, MESSI! 1-0: It had to be him! Messi receives the ball outside the box, takes a touch to control and fires into the bottom corner! Magnificent goal at the perfect moment!
Alvarez and Lozano are replaced by Antuna and Jimenez.
Hector Herrera picks up a yellow card.
Di Maria and Mac Allister are replaced by Palacios and Romero as Argentina look to tighten up.
Molina has a go at goal from the edge of the box, but snatches at that shot and blazes it way off target.
Messi looks to wriggle through the defence again, but the ball is taken off him this time.
Messi plays a one-two off Alvarez and drills the ball across goal, forcing Ochoa into a save. It's ruled to have gone beyond the byline before Messi reached it, though that was a tight call.
Argentina are doing their best to keep hold of the ball and run the clock down at every opportunity.
Messi initiates an Argentina counter and works the ball to de Paul, but Mexico manage to get it out of play.
GOAL, ARGENTINA, FERNANDEZ! 2-0: Fernandez curls one in with his right foot from out wide -- an expertly placed finish that hits the top corner! Argentina are on course to qualify!
We're into six minutes of stoppage time. There is time still for Mexico to salvage a point.
FULL-TIME: ARGENTINA 2-0 MEXICO. A piece of Messi magic and a fabulous Fernandez finish have put Argentina in pole position to qualify for the last 16. What a response to a terrible start to the World Cup!
