Saudi Arabia would progress to the last 16 with a win
A Mexico win would see them through if Poland beat Argentina
If that games finishes in a draw or Argentina win, Mexico would need to win by at least four goals
HT: Mexico 0-0 Saudi Arabia
Mexico had 11 shots in the first half of this match. That's the most they have managed in the first half of a World Cup game since 1994 against Bulgaria.
That was a round of 16 match - they lost 3-1 on penalties after a 1-1 draw. Bad omen?

The Poland goalkeeper has made six saves tonight, his highest total in a single match in the World Cup.
Excluding penalty shootouts, he has become just the third goalkeeper since 1966 to save two penalties at a single World Cup tournament, after Brad Friedel (2002 for USA) and Jan Tomaszewski (1974 for Poland).

Argentina will be reasonably pleased. They didn't get the penalty but they have created chances and it feels inevitable. While it's still 0-0 we'll have to wait and see.

Mike: Obscene decision. This has been the worst perform by officials I have ever seen!
Squarewindow: Firstly, the ball had already gone. Second, it was accidental and a genuine attempt to go for the ball. Third, the ref spent at least 45 seconds watching replays so how is it a clear and obvious error? Awful decision.

Pablo Zabaleta
Ex- Man City and Argentina defender on BBC One
Hopefully we can score a few goals and then capitalise more on our chances. Argentina have been ok but they need to move the ball a lot quicker. Find Messi around the 18 yard box, make some combinations and that's the only way to score. Poland in the first two games are defensive and keep that defensive shape very compact which is difficult to break down.

It's a really good delivery into the box and it was an excellent chance just missed. Much, much better from Saudi Arabia.
Saudi Arabia 0-0 Mexico
The half-time whistle goes.
Mexico had the better chances but both sides are out as things stand.

Herve Renard needs to give one of his infamous team talks at half-time.
"YOU WANT TO STAND NEXT TO HIM?? YOU WANT TO TAKE A PICTURE WITH HIM??"
Wouldn't want to be in that dressing room at the break.
Saudi Arabia need a win to go through to the round of 16.
Saudi Arabia 0-0 Mexico
Rare enough Saudi chance as Ali Al Hassan's diving header goes well wide.
Saudi Arabia 0-0 Mexico
Good defending by Mexico's Jesus Gallardo to stop Feras Al Brikan being in one on one. Too slow really from the frontman there.
Poland 0-0 Argentina
It has been all Argentina, but they've wasted all the chances they have forged.
Top of the list is Lionel Messi's saved penalty, which VAR decided - to the shock of almost everyone - to award.
We're still waiting for someone to take ownership of this group.
Saudi Arabia 0-0 Mexico
Hirving Lozano apologises to his team-mates as he totally overhits a cross out of play.
Poland 0-0 Argentina
Poor? I think they need to actually attack to be able to pass judgement on the quality of it!

It's been really poor from Poland from an attacking point of view.

Am I the only one glad it was awarded a penalty? Goalies think they can do what they want. Amount of times goalie punch strikers in face or completely take them out after a shot and nothing happens to them. Anywhere else on the pitch if you touch the player after they've played the ball it's a foul

Here are just two of the many chances Argentina have spurned so far...

TT: Soft penalty but Argentina should really be up by now, best they’ve played this World Cup
Saudi Arabia 0-0 Mexico
A couple more Mexican chances blocked. Two shots and a cross in the space of 30 seconds hitting Saudi players. They need to find their shooting boots at half-time.
Poland 0-0 Argentina
On the evidence of this, it looks like Poland are going to try and nab a 0-0.
Risky, risky, risky.
