90 min +2: Willian in space down the left. He looks to sidefoot one into the bottom right from the edge of the box, but Itandje isn't going to be beaten like that.
90 min: There will be four added minutes.
88 min: A long Cameroon punt down the middle. Webo troubles Luiz a bit, though the Brazilian defender eventually mops up.
86 min: Top spot's a done deal for Brazil. Croatia have themselves a consolation goal against Mexico: 3-1.
82 min: Anyway, after a lengthy stoppage for running repairs to Gustavo, and that Cameroon sub, the free kick, 35 yards out, down the left channel. Dani Alves blasts a fairly witless effort straight into the wall. Deflected. From the corner, Webo is clattered on the lug by Luiz. The pressure's off Cameroon.
81 min: Choupo-Moting is replaced by Makoun.
80 min: Mbia is booked for upending Gustavo, who was making good along the inside-left channel with some haste.
79 min: Willian tries to find Fred in the middle, but the cross is deflected and the striker's offside.
77 min: It's just a pleasant kickabout now, this. Mbia threatens to break down the inside-left channel, but there's no real purpose in his romp.
74 min: Salli is booked for toe-punting Dani Alves on the instep. Ooyah, oof.
72 min: A change for Cameroon, too, with Aboubakar - a player who's put in a decent shift in this game, his last act a delightful little backheel from the centre circle that sent Salli into acres of space down the left and momentarily wrongfooted the hosts - being replaced by Webo.
71 min: Neymar jars his knee a little, and Scolari is taking no chances. The striker looks fine, in that he's wandering off the field without limping or grimacing, but he's instantly replaced by Willian. Precautionary, and very sensible. Neymar has been excellent this evening.
70 min: It's end to end, if we don't count either final third. First Salli has a probe down the left, then Neymar embarks on a skitter down the middle. But both young men are soon stopped in their tracks.
68 min: Neymar should be clear in the Cameroon area, straight down the middle. But he's overly eager to reach Ramires's low crossfield pass from the right, and is rightly flagged offside. The hat-trick will have to wait.
66 min: Brazil would obviously like another goal or two, but there's a sense that everyone's happy enough at the moment. Brazil are back in winning ways, while Cameroon have put on a decent show. No real urgency being shown by either side
63 min: Ramires comes on for Hulk.
62 min: Neymar attempts to burst past Nyom down the left with a sassy snatch of skill, gripping the ball between his feet and jumping. But instead of attempting a simple Cuauhtemiña, the rabbit hop patented by Mexico's Cuauhtémoc Blanco back in the 1990s, he looks to run the ball up the back of his heel while in mid-air and flick it over his head. It doesn't come off, and Nyom rather refreshingly clips him round the lug for his cheek as the two jog back upfield. Neymar doesn't look happy about it, but if you try these things, this is what's going to happen.
60 min: Fernandinho is spoken to by the referee after a little tug on Salli's shoulder. He's in real danger of going in the official's little book soon, if he's not careful.
59 min: Cameroon make a change: Moukandjo is replaced by the Lens winger Edgar Salli.
56 min: Brazil are stroking it around the back. The jangling nerves seem a long time ago now. Contentment reigns.
54 min: Fernandinho clatters into Bedimo, as the busy left back looks to make ground down the wing. Not the greatest challenge you'll ever see. Bedimo does an awful lot of rolling around.
52 min: Brazil appear to be in the mood to blow away a few cobwebs. They're coming forward in waves. Waves.
48 min: A fast start to this half all right. Fred has a whack from distance, his low fizzer going in at the bottom left but palmed out of play by Itandje. Brilliant save. Then from the corner, Enoh body checks Neymar down the left and should see his second yellow, but the ref is lenient. From the free kick, Neymar's dipping shot from the wing is tipped over. And from the resulting corner ...
47 min: Two early chances for Hulk. He kicks the ball against his own ankle and out of play when clear down the right. Then moments later he's free down the middle, but Bedimo tackles him in the penalty box brilliantly. If that was mistimed, Cameroon were in all sorts of trouble.
We're off again! A change for Brazil. Fernandinho is on for the very poor Paulinho. Cameroon get the ball rolling again, and then test it for pressure by blasting it into orbit. After 10 seconds, it falls back to earth, and is gathered by Julio Cesar. Meanwhile for those of you who like bowing, scraping and furiously tugging your forelock celebrity spotting, Prince Harry's in the crowd at this game. Here he is behind a balcony, striking the sort of stiff-backed pose favoured by your old-fashioned despots. I'm sure he'll look more relaxed when he rocks up at Wimbledon in a few days, as part of what must be a very gruelling schedule.
43 min: Paulinho misplaces another pass, and Enoh is able to make good for the Brazilian box, down the middle of the park. Luiz is forced to cynically hack him down. That should be a yellow, but there's no card. It is a free kick, though, 30 yards from goal. Moukandjo pitching-wedges the ball into the area, whereupon a minor stramash breaks out. Eventually Dani Alves blooters clear, but once again the home defence didn't look particularly secure.
41 min: The Brasilia crowd are much happier right now. There was some genuine concern back there, with Cameroon briefly in the ascendency. Cameroon don't appear to be in any sort of mood to give up the ghost quite yet, mind you, despite going behind again. What a dismal showing in their first two games, a shame they didn't perform like this earlier. They're demob happy today, anyway.
39 min: Nyom embarks on what can only be described as a Garrinchian wander down the right. It's a baroque ramble, beating four men! Then he blooters a deep cross to the far post, where Dani Alves is forced to dispatch the ball behind for a corner. Moukandjo has a dig from distance at the taking of the resulting set piece, billowing the side netting, Julio Cesar always covering.
37 mins: Hulk has a batter towards goal from 25 yards. It's heading into the bottom left, a really decent whack, but Itandje is down well to parry round the post. From the resulting corner, Luiz can't guide the header goalwards.
33 min: Not exactly. Moukandjo's delivery ends up at the feet of Mbia, on the edge of the area, to the left of goal. Mbia looks for the top right, and that was whistling goalwards in a very dangerous manner. Fortunately for Brazil, the ball's deflected out, and the next corner comes to naught. But these are very worrying signs for the hosts.
32 min: Nyom and Mbia triangulate down the right, forcing a panicked Luiz to intercept. But he can only slice out for a corner. Can Brazil deal with this one better?
29 min: Bedimo is in space down the left, and he's released towards the box by a lovely sliderule pass from Moukandjo. But he went too soon. Offside. Brazil are very worried, and all over the shop at the back. Have they started thinking the unthinkable?
24 min: Cameroon were looking good for a while before the goal, and they make it upfield again, Enoh jigging down the inside-right and shooting, the ball deflecting off Dani Alves and out for a corner. From that corner, another corner. From which ...
21 min: This is also in danger of turning into a masterclass of comedy from Fred. Paulinho enters the Cameroon box down the left. He's in acres. A low ball towards the big striker, six yards out. Fred falls over. He first tries to nudge the ball goalwards with his buttocks, then lunges to nut it over the line while on all fours. But Itandje, in a DH Lawrence style tangle with him on the floor, gets to the loose ball first. What slapstick nonsense. I'm beginning to feel for Fred now, he's so desperate to score and get his critics off his back, his motor skills have gone.
20 min: This is already in danger of turning into a masterclass from Neymar, who meets a dropping ball on the edge of the Cameroon area, just to the left of the D. He swings a lazy left leg, and volleys gorgeously goalwards. The ball's going to crash into the net, just under the bar, but Itandje parries into the air, and Cameroon clear.
15 min: Haw. Some old-school tactics from Nyom. He's chasing a long Brazilian punt down the left, with Neymar. The ball goes out of play. Nyom shoves Neymar into the bank of photographers behind the goal. Bad idea, though, because ...
14 min: A free kick for Cameroon, in the middle of the Brazilian half. Moukandjo launches it into the Brazil area. He very nearly finds the head of Aboubakar, six yards out, but the ball flies through to Julio Cesar, on the line. Any touch there, and it was an opening goal, because the Brazilian defence were sleeping there. Where were Thiago Silva and Luiz? Not anywhere near making a clearing header, that's for sure.
13 min: The Estadio Nacional in Brasilia is a fairly quiet and anxious place right now. Because Cameroon are on top right now. Aboubakar rolls a pass down the left for Choupo-Moting, who fires low into the area from near the byline. Luiz is forced to hack clear. Brazil started very strongly indeed, but they're looking nervous at the moment.
11 min: Enoh is booked for a pretty damn clumsy scissor challenge on Luiz. It wasn't full-blooded, and there seemed no malice. But it deserved censure.
9 min: Brazil don't look particularly solid at the back. Enoh goes on a wander down the left, and sends a low cross into the area. It's deflected back to Aboubakar, on the edge of the box. He's got time to take a touch and lamp a shot towards the right-hand side of the Brazilian goal. Not totally sure Julio Cesar would have got to it, but fortunately for Brazil, Thiago Silva is there to block. The resulting corner is a waste of time, but that will worry the Brazilians.
7 min: In between those two Fred chances, a half-chance for Cameroon to break clear on the Brazilian goal. Paulinho misplaces a pass in the midfield, and for a second it looks like Aboubakar will have a clear run down the inside-left channel from the centre circle! But the ball gets caught between his boots, and he can't get a steam on. Brazil got away with that one.
5 min: Another Fred shot, another one that's blocked, as he's sent into the area down the right channel by Hulk. But he's getting into positions. It only needs one to go in, doesn't it. The corner's swallowed up by an unchallenged Itandje. "Nice that you mentioned that match in 1975, that Cubillas goal still bring chills in my spine, specially since there's so little to cheer about Peruvian football now," writes Eduardo Villanueva of Lima. "But Brazil didn't play with a full squad in the Copa America that year. For reasons I'm no longer recall, they decided to use only players from Minas Gerais; the match itself was in Belo Horizonte. The reverse fixture in Lima was 2-0 for Brazil and Peru only went through the finals thanks to cheating by Peruvian officials during the drawing of lots."
3 min: Fred's misery continues. Neymar and Hulk combine down the right, the latter sprung free into the area. Hulk, to the right of goal, cuts the ball back for Fred, who should send a first-time slapshot into the net, Itandje having followed the ball when Hulk had it down the right. But his shot is snuffed out at source, blocked immediately by Matip.
2 min: Neymar takes, Brazil having loaded the box. The execution is appalling, chipped over every single yellow shirt and cleared easily by N'koulou.
And we're off! Brazil get the ball rolling. And within five seconds launch a Watford-esque long ball down the middle. Cameroon clear. But Brazil are soon coming back at Cameroon, Hulk racing down the right. Bedimo hauls him back by the face, and this is a free kick in a very dangerous position, just outside the Cameroonian area.
