WHAT A SAVE!
Willian's pace beats Carlos Salcedo...again...and he shapes up to smash it towards goal. It's flying with so much power but Guillermo Ochoa is equal to it, getting two strong hands behind it and keeping his side within touch of this game.
Brazil 1-0 Mexico
Brazil have now overtaken Germany as the top scoring team in World Cup history with 227 goals.
Nice.
Brazil 1-0 Mexico
Oosh!
Carlos Vela whips a delicious strike towards goal but Alisson gets his fingertips on the end of it just in time.
Good effort.

I was expecting the net to bulge. Herrera just switched off and Paulinho had a really good chance to put Brazil 2-0 up.

Bad news for Brazil.
Casemiro has picked up a yellow card, meaning he will miss the quarter-final should Brazil make it through, after a tackle on Hirving Lozano.
Brazil 1-0 Mexico
Neymar is coming to life. He produces a nutmeg before receiving the ball back in the box. It eventually falls to Paulinho but his effort is straight at the keeper. He had so much space too...

Brazil are on the front foot. Mexico have responded well, and they are trying to get back into it, but Brazil are working hard even without the ball.

Brazil 1-0 Mexico
Neymar has scored six goals from 38 shots in World Cups - it took Lionel Messi 67 shots and Cristiano Ronaldo 74 shots to score as many.
Brazil 1-0 Mexico
Neymar has a pop from distance but it's never testing Guillermo Ochoa. Brazil are up and running. Mexico need to find a spark.
Brazil 1-0 Mexico
Willian is enjoying it today. He runs with the ball for the length of the pitch before he's eventually dragged back by Hector Herrera.
It's a foul and he's got a yellow. That means he's out of the quarter-final if Mexico make it.

Lucas: Another 3 yard screamer from Neymar
Dennis: The World's Best scores! Neymar created and scored it
Michael: Neymar does more than people realise. Defenders always have to watch him, and he creates space. People were moaning about Spain's boring passing yesterday, and now they're moaning about Brazil's pace and skill. No pleasing some people!
Brazil 1-0 Mexico
The ball comes over to Hector Herrera at the back post but his strike is blocked. Carlos Vela then dribbles through several players before he's brought down in the box and Mexico think they have a penalty.
No penalty given, no VAR but it's the right decision.
Brazil 1-0 Mexico

OK so it just got pretty lively in here. Doubt there would be a more popular scorer among the joyous Brazil fans.
But spare a thought for Jesus Gallardo who just moments ago had Hirving Lozano driving in on his left but blazed over the bar instead of picking him out.
How quickly fate can turn in the World Cup knockout stage.

Unbelievable skill from Neymar. He puts one finger across his lips as if to say 'be quiet, I will deliver'. One touch from Willian, before he puts it across the box, and Neymar taps it in.
Brazil 1-0 Mexico
Mexico respond straight away from the kick off and win a corner kick. It's their fourth so far.
Neymar
Neymar starts the move, bringing players with him as he runs across the box before backheeling it to Willian.
The Chelsea man fires a low ball across goal and with Gabriel Jesus and Neymar coming in, one was bound to get a touch on it.
As it is, it's their national hero who does. Two goals at this World Cup for Neymar.
Brazil 0-0 Mexico
Jesus Gallardo tries to catch Brazil on the counter. He has options to his left and right but space down the middle.
He aims for the space but tries an audacious effort which sails over the bar.

Here's one we can answer...
Bigger question in my office is not whether or not Firmino or Fernandinho should play but if the BBC reporter named Patrick Jennings is related to the Pat Jennings...end the suspense please!

No he isn't!
