Poland 0-1 Argentina
Danny Murphy
Former England midfielder on BBC One
It's going to be difficult for Poland to create an urgency and intensity in this heat. It's a warm evening here in Qatar.
Poland 0-1 Argentina
Saying that, Argentina are waltzing through their packed defence, never mind a less well-manned one.
Poland 0-1 Argentina
Still no sign of Poland opening up to attack Argentina. It is so dangerous.

Great vision from Messi again. He just sees all the pictures.

Argentina continue to batter the Poles.
Nicolas Tagliafico is found in space on the left and his low cross picks out Alexis Mac Allister for a low shot that he blasts straight at Wojciech Szczesny.
Guess who picked out Tagliafico with a glorious pass? I don't even need to type it. You know.
Saudi Arabia 0-2 Mexico
Mexico have a corner. Henry Martin gets his head to it but not enough power.
Another corner though.
Saudi Arabia 0-2 Mexico
Saudi Arabia's heatmap tells a story.
They have offered nothing going forward.

Saudi Arabia need to score three goals. I don't see that happening at all.
Poland 0-1 Argentina
I pity the Poland fans going through this. It might be one to hide behind the settee and come out praying for good news when it's all over.

Saudi Arabia are sloppy, giving the ball away in a dangerous area, they almost get punished again.
They look shell shocked.

Mexico just need one goal to overtake Poland on goals scored and go through. As things stand right now. Everything is subject to change.
Poland 0-1 Argentina
Argentina's first change sees Marcos Acuna replaces by Nicolás Tagliafico. Angel di Maria is also off, with Leandro Paredes on.
Saudi Arabia 0-2 Mexico
Mexico have the ball in the net again but this one is disallowed.
Hirving Lozano plays the ball through to Henry Martin. He controls it and Lozano takes back over and steers the ball into the bottom corner.
Sadly Martin was a few inches offside.

It is some noise now at Stadium 974.
But the real drama at the moment is whether Poland can hang onto second place.
Argentina look in the mood for more goals - and that is very bad news for Poland.
Poland 0-1 Argentina
It feels like the picture is altering by the minute here. Twists and turns.
You have to think we've got more drama in store yet.

Wayne: No excuse at all for a team of Poland’s quality to be playing this negatively from the start. Getting what they deserve

A thing of beauty.
