Ready to rock? The Brazil players are. They limber up at the top of the concrete steps leading down to the pitch. And they are also looking down on the other three teams in the Group A table as things stand. Will that change over the 45 minutes? We're going to find out.

While the goat had to stay outside the Estadio Nacional, someone who did manage to get through the turnstile was Prince Harry. The British royal, who is in Brazil to support his charitable work, is also set to watch England's final match against Costa Rica tomorrow. I know which one I'd have been looking forward to the most...

BBC Africa's Manuel Toledo on Twitter:, external Goat Brazil!!! This poor animal couldn't get into Brasilia's stadium.

You've goat to be kidding me. That is baaaaaa-d. As are those puns.

Pressure? What pressure? Two-goal hero Neymar is the coolest man in the stadium, stopping to pose for a few pictures with the Cameroon bench before wandering down the tunnel for his half-time orange.

"The first half ends to rapturous cheers after Neymar, Oscar and Paulinho combine to tee up Hulk for what would have been an incredible team goal, only for the striker to fluff his lines. Brazil have been great going forward but unconvincing at the back, and a better calibre of opposition than Cameroon might well have been leading at the break."

"Mexico started the strongest but they will be a little bit disappointed they have only had one real opportunity. Croatia have been in poor midfield, they haven't really created anything. Luka Modric and Ivan Rakitic haven't done what you expect them to do in midfield."

And seconds later the half-time whistle is sounded in Recife. That was not as dramatic as the action in Brasilia, but there's no shame in that. Croatia and Mexico has been the Emmerdale to Brazil and Cameroon's Eastenders.

"It has been a wonderful game, end-to-end stuff, attacking football, defensive mistakes. When his country needs him though, Neymar has been absolutely sensational."

And that's the last action of a breathless first half. Phew. Go and grab a cup of tea and let your heart-rate settle down. We've got another 45 minutes of that wonderful, wonderful stuff to follow.

Oh my word! Brazil almost score one of the great World Cup goals. Neat, intricate build-up play ends in Hulk prodding wide. What a goal that would have been.

Every ball in the box it's heart in mouth time. There is panic- Brazil do not look comfortable and Cameroon could easily be drawing this game.

The fans inside the Estadio Nacional will be getting Wimbledon-style neck-ache at the moment. The ball is pinging from end to end. Cameroon send a free-kick into the mixer before Brazil break clear. One minute of added time.

David Luiz shows us the PlayStation footballer that Gary Neville famously described, the Brazil centre-half dancing forward with the ball at his feet before clumsily losing possession on the edge of the Cameroon area. Both sides are being very careless in possession. Like me with my house keys.

"After a slow start Mexico are getting back into this game. Oribe Peralta just made a fantastic run and got in behind the Croatia defence, but just as he was about to shoot he slipped."

Croatia struggling for chances at the moment - but as things stand they are going home. Mexico are well-organised and proving difficult to break down.

"Chants of "Neymar! Neymar!" engulf Estadio Nacional as Brazil retake the lead and as the 22-year-old celebrates, pointing to the heavens and asking for even more noise from the crowd, coach Scolari pulls David Luiz to the touchline and gesticulates wildly with the centre-back as he tries to get a number of points across. "Mark your man" might well be one of them."

This game could end up 6-5 at this rate. Back come Cameroon through Eric Choupo Moting, whose low shot is easily gathered by Brazil stopper Julio Cesar.

"Just as Cameroon were getting into the game, Brazil get the goal.

"Neymar drove in from the left, I don't know what Allan Nyom the right-back was doing because he leaves a massive space for Neymar to run into. He moved it onto his right foot, Charles Itandje went down far too easily in the Cameroon goal and he just places it past him."
