Former Manchester City defender on BBC 5 Live

We saw an Argentina side that were pushing and pushing but Saudi Arabia were comfortable in the way they were defending.

At times we think football is predictable, and then things like that happens and you are reminded about why we love football.

As long as you are committed and take the opportunities you have, anything is possible.

Graeme Souness
Former Scotland captain on ITV

That was a shadow of any Argentina team I have seen. They were a shadow today.

Clinton Morrison
Former Republic of Ireland striker on BBC Radio 5 Live

Argentina were poor in the second half. I thought they had a few more gears to go through.

Saudi Arabia put their bodies on the line. They were brilliant. They have a threat up front.

Argentina's defence lack a lot of pace, that is a problem.

Mark Chapman
BBC Radio 5 Live presenter

That is seismic.

Joe Cole
Ex-Chelsea and England midfielder on ITV

That winning goal will inspire a generation. This is the World Cup started for me. This is an unbelievable result.

Biggest World Cup upset of all time?

Thumbs up for yes, thumbs down for no.

Clinton Morrison
Former Republic of Ireland striker on BBC Radio 5 Live

What a game. It was the best game in the tournament so far. It is fantastic.

First half, Saudi Arabia were nowhere it. They were by far the better team in the second half.

Argentina could have played all night and I don't think they would have scored.

Saudi Arabia thoroughly deserve it.

Andy Cryer
BBC Sport in Qatar

The Saudi Arabia fans lucky enough to be here to witness this will never forget the moment they beat Lionel Messi's Argentina.

One gets the feeling their celebrations will go on long into the night after a heroic second-half rearguard effort.

But what now for Argentina? Their fans seem completely stunned as they already start filing out in almost silence.

What a contrast to a couple of hours ago when the blue and white shirts were in party mode.

Incredible. One of the World Cup's biggest ever shocks.

Wonderful, incredible scenes of celebration on the pitch. Saudi Arabia players are hugging, smiling, crying.

They run to the wall of green and celebrate with their fans.

What a moment.

That is sensational! What a result!

Argentina cannot believe it.

It is a monumental result.

Just wow!

All over!

A HUGE, incredible win for Saudi Arabia and one of the biggest upsets in World Cup football.

Argentina, one of the pre-tournament favourites are stunned.

What a performance, what a result.

Argentina are firing crosses in, Saudi Arabia are holding on. Still we play...

Mark Scott
BBC Radio 5 Live commentator

Argentina are on borrowed time.

We're into the 13th minute of added time...

Clinton Morrison
Former Republic of Ireland striker on BBC Radio 5 Live

This might end when the keeper kicks it.

Mark Scott
BBC Radio 5 Live commentator

That was a save for the cameras.

Argentina win another corner. Marcos Acuna sends the ball in, Saudi Arabia clear but the ball is played back into Julian Alvarez who looks certain to loop a header into the far corner but Mohammed Alowais makes another HUGE save!

Saudi Arabia are almost there!

Mark Scott
BBC Radio 5 Live commentator

That is great news that he is able to put his thumbs up and he's awake.
