Poland 2-0 Saudi Arabia
One almost brings two for Robert Lewandowski, and it probably should truth be told.
He shows brilliant footwork to jink in and out of the Saudi Arabia defence and Lewandowski tries to dink it over the advancing keeper, but Mohammed Al Owais' strong hand keeps it out.
Poland 2-0 Saudi Arabia
Saudi Arabia are still attacking to be fair to them. They haven't been anywhere near clinical enough to win this game, though.
That goal was Robert Lewandowski's 77th for Poland by the way.

Al Malki was just caught on the ball. If you're the last man in defence, you've got to make sure you don't take too many chances.
Against Robert Lewandowski, that's always going to be a dangerous thing to do. He was too lax with his first touch.
It's hard on Saudi Arabia but they will have another chance in this group.

Robert Lewandowski
The main man has his World Cup goal!
This is a nightmare for Abdulelah Al Malki and Saudi Arabia. He takes a heavy touch and is robbed by Robert Lewandowski.
The 34-year-old composes himself and just slots under the keeper and into the bottom corner.
In his fifth World Cup game he's got his first goal. He is visibly very emotional after it too. What a player.

Saudi Arabia have switched Saud Abdulhamid, who was arguably their best player in the first half, to the left. I'm not sure that was the best idea. He's nowhere near as effective there.

Dragged wide!
Saudi Arabia attack down the left and the ball breaks for Feras Al Brikan but he drags a left-footed effort wide of the far post.
Will the equaliser come? Just over 10 minutes remain.

You can see the tiredness there for Saudi Arabia now. Unfortunately for them, their changes have not had a positive effect in any way whatsoever. You wonder what the quality is like when you dig down into that squad.
Poland look more comfortable - they've been here before and are slowly but surely getting more into this game in an attacking sense.
Poland 1-0 Saudi Arabia
Arghhh Poland!
They work an opportunity to release Robert Lewandowski but the final pass is overhit and Mohammed Al Owais is able to come out and clear.
They are missing some chances. Could it be costly?

Sho: Saudi's finishing had been horrendous. Should be winning this game comfortably. Miles the better team.
Christian Evans: Saudi Arabia really should be level in this match, they are actually decent to watch going forward! Need to be clinical.

Image source, Getty ImagesThe game has lost a little bit of structure. It's almost Dutch total football from the Saudi Arabians, which is very difficult to mark.
It's either that or they're just getting over-excited.

Another change for Poland.
Arkadiusz Milik, who hit the bar about five minutes ago with a diving header, comes off for Krzysztof Piatek.

Herve Renard is full of energy on the touchline. He's been running and down, directing his players, screaming.
He's had to take himself away for a swig of water.
Wojciech Szczesny lines up another shot and completes an easy save.
Can Saudi find an equaliser - and then winner - with 20 minutes to go?
Poland 1-0 Saudi Arabia
Poland might have hit the bar and the post but Saudi Arabia (purple dots) have had the better of the chances so far in this game, according to the xG.
The bigger the dot, the better the chance. There are a few big old dots there for Saudi Arabia...

Image source, Getty ImagesMilik thought he'd done everything right there. If it had been 2-0, it would have been game over.
Saudi Arabia have been breaking through the lines. Poland will have been getting more worried about the last few minutes - they've been getting more and more stretched.
Herve Renard did a great run down the wing - but sadly he's the manager. He's very excitable in his white shirt, isn't he?
Poland 1-0 Saudi Arabia
Are Poland going to rue these missed chances?
Robert Lewandowski meets a cross from the right, but his initial flick with his right foot glances into his left foot and cannons back off the post.
His wait for a World Cup goal goes on.
Poland 1-0 Saudi Arabia
That will be a warning for Saudi Arabia.
They will naturally chase this game the longer it goes on, but they'll need to be wary of leaving too much space for Poland.
Poland 1-0 Saudi Arabia
Off the bar!
A cross from the left is met by Arkadiusz Milik but his diving header crashes back flush off the bar.
That would probably have been the game if it had gone in.

First change for Poland.
