FT: Bosnia-Hercegovina 3-1 Iran (Iran go out)
Nigeria and Argentina through to knockout stages
Messi scores double before being substituted
Iran have had a real go since going behind. Asmir Begovic has to make a great save to keep out a deflection from his own defender, but the flag was up for offside. Iran throwing men at this one though.

"Nigeria are doing what Iran and Bosnia have been able to do and that's stifle Argentina for large parts of the game. They're stifling that space in central midfield where Messi wants to drift into. They've done a good job of making it hard for Argentina."
That's how good the atmosphere in Porto Alegre is, it's even better than scoring at Scunthorpe...
What a hit! Another piledriver from Angel Di Maria, forcing Vincent Enyeama into a flying save.

A very open and entertaining game in Porto Alegre. Argentina's magic four up front are combining at will, while Peter Odemwingie has thrashed a left-footer over the top from 20 yards. More goals in this one. More goals in this World Cup...

"It's no more than Bosnia deserve but it has woken Iran up and they should be level."
Maybe Iran's gameplan is not all over! They hit the bar seconds after going behind, Masoud Shojaei drifting a chip onto the face of the crossbar. Lovely effort.
Image source, AFPThe problem with playing for a 0-0 is when you concede early on, it's all over.
Bosnia take the lead with a cracking goal from Manchester City man Edin Dzeko. He drifts away from a defender before clipping a left-footed shot in off the base of the post from 25 yards. He looks livid - cheer up Edin!
Image source, AFPIran have set up shop for another 0-0 - though they did play like this against Argentina and then had two good chances on the counter-attack late on. It's a patient game.
Paddy Emmerson:, external What a start and what a way to get everyone's mind back on the football. #Messi proving why he is the best in the World.
Tunde Giwa:, external Super Eagles will go very far in this tournament. Fearless, firm, gritty, unblinking, unintimidated, unshrinking, unyielding...

"Nigeria are doing a good job so far and are really showing ambition on the ball. They just need to be a little bit careful when they lose it."
Lionel Messi whips in a free-kick from deep, John Mikel Obi has to stretch to meet it and almost heads into his own net, testing goalkeeper Vincent Enyeama but the Lille keeper makes the stop.

Steve Claridge, BBC Radio 5 live
"Iran are still lucky to still be in this and have been pretty negative. Bosnia have completely dominated from the start."
Lionel Messi and James Rodriguez of Colombia are the only players to score in all three group games.
Porto Alegre is dancing to the Argentine beat, their fans are so loud, it's a truly impressive effort. As it stands both of these sides will be going through.
Mark Levy:, external What a start #ARG v #NGR! This is football. Let's face it, no one is missing England.
Scott Kelly:, external Messi is thriving in that central position playing behind Higuain/Aguero. Keep it like this the Argies could go all the way.
Andrew Roulston:, external Messi, Higuain, Aguero, Di Maria and have Lavezzi on the bench. Argentina have to be favourites for the World Cup now.
Lionel Messi has now hit nine goals in his last eight games for Argentina as he translates club form to country. Is he finally grabbing a tournament like we know he can do?
Three in three.

"Lionel Messi looks like he is ready for business. Yes, he has been deciding matches but he hasn't taken games over at this World Cup the way we know he can. But he looks really motivated out there. He's talking to his team-mates and Nigeria don't know how to deal with him."
