Apparently Tim Krul was out practising penalties at half-time. Will the Newcastle man be the key protagonist again this evening?

A picture paints a thousand words...

Javier Mascherano slides in Lionel Messi down the sides - but he's offside. Almost a glimpse of danger for Argentina.

Have it! Smashed away into the stands by Ezequiel Garay, under no pressure, but he's not having a David Luiz meltdown, he's actually smart as his boot had come off. Get rid.

The Dutch finally get the ball to Arjen Robben and he goes down, with Martin Demichelis in the book to boot.

"That substitution means Daley Blind will play as the third centre-back, with Daryl Janmaat at right-back and Dirk Kuyt switching over the the left. Everyone else will stay the same."

Referees are not having bookings in the World Cup are they? Another clattering challenge from Stefan de Vrij goes unchecked. Play on!

Chris Gilbert:, external You would expect both teams to take more risks in the second half. Neither team will want it to come to a shootout.

Who fights monkeys:, external Who would want to get to a final against Germany the way they're playing at the moment?

Arthur Veldhoen:, external I'm beginning to think a gentle beating by Argentina would be highly preferable to what the Germans would do to us in the final.

Golf legend Gary Player tweets:, external Half time at the World Cup. #ARGvNED. No one has scored yet. Not even Germany.

The Dutch kick off, and Dirk Kuyt is now on the left wing.

Daryl Janmaat is on in place of Bruno Martins Indi. I think that will be a flat back four and Dirk Kuyt's second position of the evening. It won't be his last!

Here they come, and it looks like the Dutch are making a change. Maybe of system...

"If Sao Paulo had a Lord Mayor's Show, this would be on after it. Belo Horizonte staged a World Cup semi-final that would be remembered forever as Germany thrashed hosts Brazil 7-1 last night. Here, Argentina have been on top but this has been deadly dull. Lionel Messi has shown touches of class but the Dutch match-winner Arjen Robben has been invisible."

Social media comments from around the world are being translated and curated by the BBC's multilingual World Cup Twitter conversation, @viabbc., external

Richie 10 (Spain):, external Argentina are getting tired and Netherlands are saving everything for the second half.

Ugur Karagozlu (Turkey):, external Looks like Argentina will score using Bruno Martin Indi's wing. He lacks talent and is so slow.

Cesar (Spain):, external I don't mind who wins. I like Argentine football (but not what this Argentina team is playing) and football owes a great debt to Netherlands.

Let's keep the faith though. Every game at this World Cup has eventually been compelling, if only for a short space of time. We will have extra time at around 22:50 BST and it should be cracking...

Did you know that in Groningen the Grote Markt, the Vismarkt, the Poelestraat and Peperstraat are crowded every night of the week, and most bars do not close until 5 in the morning?

Me neither. Let's all go to Groningen...

Netherlands fans watch the action in the market square in Groningen. Not quite sure what they are so gripped by in this first half.

"Very disappointing. Argentina slightly the better side without making any chances. There has been nothing to talk about. I wonder how Van Gaal will feel about this. He normally changes things but they have to get Robben into the game."

Arjen Robben has a smile to someone as they come off. He gets nearer to the ball in the tunnel then he did for most of that half.
