Even stevens so far in the second half as Giovani dos Santos gets a shot away but it's deflected into the arms of Julio Cesar.

That is close though! Paulinho lets Hector Herrera turn inside and get off a shot which flies across the face of goal and over the top.

"This second half has started with much less energy, but what we have seen is an important tactical change from Brazil. Immediately you can see the effect Bernard going up to play closer to Fred has had on the Mexico team. Miguel Layun can no longer play so high up the pitch. A very good tactical move by Luiz Scolari.

"It looks like Mexico have set a little more to counter, but for me they have to do it a touch quicker to get anything on target."

No Hulk for Brazil tonight, but plenty of support for the injured forward in the stands.

That early surge from Bernard was perhaps a false dawn as Brazil have been sluggish since. Mexico now win a corner.

Social media comments from around the world are being translated and curated by the BBC's multilingual World Cup Twitter conversation, @viabbc., external

Caroline Teixeira, from Salvador, Brazil: "If Brazil carries on playing like this, we will lose! The first half was a fiasco."

Junior Falanque, from Sao Jose do Rio Preto, Brazil: "Neymar's and Dani Alves' hair aren't bringing any luck to the team. Wake up, Braziiiiiiil!"

Oscar has moved back into the middle since that half-time change. Brazil seeing all of the ball since the break but can they force their way through the Mexican ranks?

Paul Burton:, external Expecting a Brazilian rush this half. Watch out Mexico it's gonna get hotter.

Adedamola Olanrewaju:, external Can anyone pls tell me apart from Fred who else does Brazil have as a main striker. Fred is just ridiculous.

Loki:, external Surprised that Ramires has gone off; not #bra worst player by any means... Like Bernard though; smiley face.

Bernard in straight away! Great pace down the right to get to the line and fire in a good cross but Neymar can't quite meet it. Incisive from the substitute.

Oscar then lashes over the bar. This is better already.

Rafa Marquez is down early on for Mexico after a boot to boot challenge. Mexico will need him up and running sharpish and the leader is soon up and running again.

Mexico get us under way.

Brazil do make a change at the break - Bernard for Ramires. Can the Shakhtar man do it?

Donna:, external Too much of the ref. Too many folk falling on the floor. 2nd half is sure to be a belter!

Khattab:, external Mexico are well organised. Herrera will do damage up front.

Stuart McQuitty:, external Do Brazil pick Fred to give everyone else a chance?

"Mexico will be the much happier side, they have got the ball into dangerous areas and created a couple of good chances. They forced Julio Cesar into making a good save and I think the tactics have worked an absolute treat for them."

If Brazil need to freshen it up they have Willian, Bernard, Jo and Fernandinho on the bench. Will Big Phil make a Big Switch?

So-so for Brazil in that first half. Can they step it up?

Former England striker on MOTD

"Fred has infuriated me. He has been lazy at times, it is frustrating. He has the ability and has a decent record but I'm sure the coach will be telling him he must do more."

One more game to come tonight, and I'm banking on you staying up for it.

It's the only two sides yet to kick a ball at the tournament - Russia v South Korea...

"Fortaleza pauses for breath. Brazil are, once again, struggling to find the fluent, flamboyant football we know they are capable of.

"Great credit to Mexico, they have stifled Brazil and closed down their options but they have also given just as much as they have got. Neymar, perhaps, had the best chance of the half, but Mexico drew one excellent save from Julio Cesar and went close on two other occasions. Brazil just need a bit of inspiration in the final third."

Dan, London: How is Phillipe Coutinho not in this Brazil team?! To watch him link up and provide for Neymar would be a joy.
