Feras Albrikan drops to the floor after an awkward fall when jumping for the ball. It takes up a few more seconds and Argentina's players are looking increasingly frustrated. It now feels like they'll need something special just to rescue a draw here.

Argentina have been poor in the second half.

I had them down as one of my favourites, but based on this no chance.

It can't always just be Messi. Other players have to step up.

Just FIVE minutes to go.

Saudi Arabia are on the verge of securing a huge World Cup upset here.

All the noise is still coming from the Saudi fans. What an atmosphere they are now making. Every tackle, every foul, every clearance is met with a huge roar.

There was no real power on the header, it was such an easy save.

Argentina have not lost a World Cup match in which they scored first since 1958 but it is looking increasingly bad for them now.

Lionel Messi is picked out by a ball into the box but his cushioned header is almost a pass back as far as Saudi Arabia goalkeeper Mohammed Alowais is concerned.

Argentina need a goal and at the moment I can't see where it is going to come from.

Saud Abdulhamid, who has been excellent for Saudi Arabia today, is booked for a foul. It does disrupt the play a bit for Argentina, though. Any little gain will feel huge in these final, decisive minutes.

Where would this rank in World Cup shocks?

Saudi Arabia are ranked 51 in the Fifa rankings. This is their 17th match at the World Cup. They’ve lost 11 of those, winning three and drawing two, conceding 39 and scoring 11. Their other wins came against Egypt in 2018 and Morocco and Belgium in 1994.

A big 10 minutes or so to come in World Cup history…

It can't always be Lionel Messi, others players have to step up too, but you would have expected him to at least hit target there.

... up steps Lionel Messi... and he sends it high over the bar!

Is this going to be Saudi Arabia's day? It is increasingly feeling like it.

Uh oh, there's a collision on the edge of the box and Argentina are awarded a free kick in prime Lionel Messi territory...

Football expert Guillem Balague, who wrote the biography Messi, is sitting alongside me here and, at the moment, he is shaking his head in disbelief.

When asked what the reaction will be back in Argentina, his reponse? "Absolutely mad".

There is just a sense of disbelief around here.

A defensive change for Saudi Arabia as they look to try and see out what would be a huge shock.

Sultan Alganham comes on for Saleh Al-Shehri, who scored the opening goal.

Saudi Arabia would bite your hand off for a draw right now.

Enzo Fernandez cushions a header high over the bar from another Argentina corner.

Another chance gone and a few more precious minutes eaten away as far as Saudi Arabia are concerned.

Mohammed Alowais comes flying out of his area as Lautaro Martinez this time does beat the offside trap but the Saudi Arabia goalkeeper's alertness pays off as he gets to the ball first.

A nervous silence breaks into relieved applause from the Saudi Arabia fans.

You have training drills that are attack v defence and that's what I think it will be like for the last 20 minutes.
