Into the last 20 minutes then. These two sides are heading through to the last 16, and nobody will want to face Argentina and their fans...
If Netherlands meet Argentina, I demand that we get Barry Davies back on comms, and have him alongside Dennis Bergkamp...
Mark Hendrikx:, external Seems that the Argentine defence is still susceptible to leaking goals.... Bodes well for Netherlands in the semis?
Graham Wood:, external Nigeria need a bit of Shola power to get a draw here. Bring on the Fenham Eusebio!
There's the first few signs of tiredness creeping in, this one has been played at Premier League pace throughout. I wouldn't rule out another goal or two, Nigeria still committing plenty of men forwards.
Helles Mammut:, external Arrogant and presumptuous move by Sabella. I hope Nigeria score two so that Argentina finish second in the group.
Bosnia almost sneak in a freak third as Sead Kolasinac hits a low cross which deflects off a defender and hits the base of the post. Bosnia looking comfortable, they've played pretty well in all three games and will be pleased to go back with a win.
Sadly, Lionel Messi will now never get the chance of an education by watching Jason play live.

"That's the first time I have seen Lionel Messi play live and that was an education. What a fantastic player. It's been a pleasure watching him."

We won't get a Lionel Messi hat-trick, as he is rested for the last half an hour. What an ovation! He won't get louder than that.
It's probably sensible to give him a break, as Ricardo Alvarez of Inter is on.
BBC Match of the Day commentator Dave Woods: "The last meeting between the two sides in Sarajevo in 2009, Iran won 3-2 having been 2-0 down with 20 minutes to go. Some hope perhaps for Iran?"
Nigeria are losing but going through, and it's end-to-end stuff in Porto Alegre.
A Nigeria corner is not dealt with and it falls to John Mikel Obi - but his shot is as tame as it gets. Rank.
Former United States defender Alexi Lalas on Twitter:, external Defending is dead. Long live defending.
He's a class act is Miralem Pjanic, and he now has a World Cup goal to go on his CV. Edin Dzeko finds him on the overlap, one touch kills it dead and the second steers it into the corner.
Game, set and the match. That should also seal Nigeria's qualification.

"Messi is really dictating play now and Nigeria have to find a way to stop him. He has really come to this World Cup party. Could we about to witness a Messi hat-trick?"
Lionel Messi hasn't just come to the party, he's brought all the drinks and turned up with a car full of girls.
On his A-game now, he skips away from two men across the field and eventually is fouled. This is what every neutral - and 200,000 Argentine fans in the city of Porto Alegre - want to see...
Mo from Manchester on text: Well I was sad for England...for a day, but I'm over it!! What a game, surely best of tournament so far! Got to love the World Cup!
Stats provider Infostrada Sports on Twitter:, external Lionel Messi joins Diego Maradona (1986 QF and SF) as the only players to score four World Cup goals in a row for Argentina.
You've not missed much in the other game - Iran do manage a rare attack but Fulham winger Ashkan Dejagah can't get the shot off.
Breathless stuff. Juwon Oshaniwa is booked for a reckless lunge on Ezequiel Lavezzi, Lionel Messi then flings a cross in which Vincent Enyeama has to come and claim, and the keeper then beats clear another low ball.
The fans are making a monumental din...

"Fantastic goal or really bad defending? Could the keeper have come and got it? Everyone has missed the ball and Rojo has put it in with his knee."
