Brazil hold on to reach semi-finals
Hosts to play Germany in semi-final
Luiz the matchwinner with 40-yard free-kick
Rodriguez scores consolation penalty
Hulk! Lovely touch but the decision making of a man in the Trafford Centre at 7pm on Christmas Eve.
Anything will do - and he batters a shot high and hard over the top with two men waiting for the cut-back.

"Colombia need a spark of inspiration. All the belief they had coming into this game has been drained by the goal. It is difficult for them, playing in this sea of Brazilian shirts, they will have to change something at half-time.
"Brazil meanwhile do not want half-time to come. The game is being played at a frantic pace, it is incredible, especially in this heat."

Never 10 yards! The ball is rolled to James Rodriguez and Neymar charges it down, he was never 10 yards away! Another free-kick, this time on the left wing. Good spell from Colombia.
So much space! Who was marking Juan Cuadrado? In oceans, but he hesitates and is fouled on the edge of the D.
Chance here. Central, 20 yards out. Get it over the wall and you score...
Former England defender Martin Keown
"Brazil's ball retention is much better than in the Chile game. Nothing works harder than the ball. Colombia are desperate, they just can't get the ball back."
Social media comments from around the world are being translated and curated by the BBC's multilingual World Cup Twitter conversation, @viabbc., external
Diego Montes (Spain):, external "Is the Colombia defence still in the changing rooms?"
Juanillo (Spain):, external "Unrecognizable Colombia. Unrecognizable Brazil."
Rosendo Garcia (Peru):, external "Carlos Sanchez let the man go, good run from Thiago Silva. Colombia are nervous, Brazil commanding and gaining territory."
Ricky Lee Everett:, external "Colombia should just go home now or slap themselves to wake up quick - they are all over shop. Totally different side tonight."
Tom Mizkowski:, external "Brazil doing a job on Rodriguez at the moment. Hope he gets an opportunity to show what he can do."
Andrew:, external "Colombia may as well be playing Shakira at the minute."
Image source, AFPColombia just take their time over a throw, just to give a breather more than anything, wise given the tempo of this game. Juan Cuadrado then has a shot charged down and the madness re-appears.
David Luiz wins it on the the edge of the box and runs it, he beats two men, another, he's right down by the corner flag when he is dispossessed.
Both teams' heads have gone here. It's a brilliant watch but a tactical disaster. Play like this against Germany and they'll be picked off like fish in a barrel.
BBC Sport Chief Football Writer Phil McNulty in Fortaleza
"Colombia's coach Jose Pekerman moves to the edge of his technical area to gesture to his players to calm down - a move that falls very much into 'easier said than done' territory in this environment. Seeing the first flashes of James Rodriguez now, though, so that will encourage Pekerman."
Image source, AFPHulk is everywhere now, thrashing in a low shot from a fine pass from Marcelo and David Ospina makes the save, strong wrists to repel Hulk's venomous strike.
How's this only 1-0?

Image source, AFP"A warning for Brazil. The breakaway was started by James Rodriguez, who ran past two Brazil players before playing a great pass. This is a huge game for Rodriguez now - Colombia are so reliant on him and he has started to drop a little deeper.
"But up until that break the Colombian players have looked overawed, they have been nervous and slow to react to everything.
"Meanwhile Hulk looks a completely different player today, twice already he has threatened from in behind the defence."

"David Luiz has got to be very careful. He comes in very deep, James Rodriguez lays it off quickly and then gets around him. It's going to be a test for these two Brazilian central defenders."
Image source, AFPChaos!
Fernandinho hacks down James Rodriguez in midfield, the Colombians all pile in around the referee but the men in red take the free-kick quickly. Nobody realises, Brazil win it back and the Colombian defence are all over the place!
Oscar has a three-on-two break but messes up his pass. You'd think this was the last two minutes the way this game is being played!
John McEnerney: , external"Maicon has done more in 20 minutes than Dani Alves did in four games!"
Said Madrid:, external "Colombia defending very deep and disorganised. Brazil with very little causing havoc."
Alexander:, external "Thiago Silva is the best defender in world for me, in second is Hummels, they both score today, great positioning, and composed."
The first piece of James magic!
Good game this now, James Rodriguez spinning away from two men in the middle, committing and beating Fernandinho with ease before sending in Juan Cuadrado on his right. Cuadrado has to hit it first time but takes a touch and the chance has gone.
It's breathless, magical stuff. Everything the last few games haven't been. Open, naive, brilliant...
Former England defender Martin Keown
"Hulk has got better as the tournament has gone on and is starting to look the part now."
Image source, AFPHulk is alive now! The burly forward plays a great one-two, swapping passes with Neymar before driving into space and testing David Ospina at his near post.
Brazil buzzing. First into the tackle, winning every second ball. They want it...
Brazil looking so dangerous from corners, Neymar's delivery is half cleared and Juan Cuadrado faffs about with it on the edge of the box, Not there!
Hulk takes it off him, beats a man and puts in a low cross which David Luiz attacks and almost gets to. Tremendous last-ditch clearance from Mario Yepes, who is cajoling his troops now.
Stay together...

"Now comes the test for Colombia - a goal behind early on and fighting against the sort of noise, fevered atmosphere and support that makes Brazil such a special sporting country. This World Cup has seen enough from Jose Pekerman's side to know they have strength but they will need it now like never before."
