BBC Radio 5 live"We're starting to see fatigue and a lack of concentration kick in for both teams now. Both Argentina and Switzerland are making needless mistakes.
"It's going to be either a wonder-goal from Argentina or a scruffy goal from Switzerland to break the deadlock. It's a toss of the coin which way it will go. Or of course there are penalties."

A sea of red shirts has formed in front of the Swiss box.
Argentina cannot find a way through. More frustration as Rodrigo Palacio hacks down Valon Behrami.
This is so untidy.

Harry, Leicester: Stop calling for Tevez, people. He's not in the squad because he couldn't be implemented in the team alongside Messi. He forced Messi into a less influential role, and Argentina haven't missed him.
Andrew: Argentina are making hard work of this. One mistake or one moment of brilliance will settle it.
Ravi, London: If England had been dealt Argentina's draw we'd be through to the quarter-finals. Argentina have been so poor.

Argentina want this done and dusted before penalties.
Substitute Rodrigo Palacio forces another save with a glancing header.
Switzerland are having to dig deep. Can they hold out for penalties?

BBC Radio 5 live"I thought that was in - from the angle we had it was a slow motion loop into the net.
"Gelson Fernandes will be important for Switzerland in extra time, he is a fit lad, happy to get up and down the pitch. But he will have to be careful - he is on a booking already."

Chaos in the Swiss area. Ezequiel Garay gets on the end of Angel Di Maria's corner but Diego Benaglio deals with the danger.

MOTD analyst"I still have the feeling that if Argentina can get it down and play it a bit quicker they will have some success. Switzerland will only play one way in extra-time - defend deep."

Wake up! Extra time has started.

BBC Radio 5 live"On the balance of play 0-0 is probably about right. Argentina had one or two chances in the second half but Switzerland should have been up at half-time. I've been impressed by them. They had a game plan, and sometimes you have to be a bit negative."

They have yet to turn up in Sao Paulo.
Switzerland will be cursing the chances they have spurned. League One finishing on the World Cup stage.

Chance for Switzerland.
A free-kick is whipped into Argentina's penalty area but Fabian Schar cannot keep his header down.
Poor. Poor. Poor.

Gareth, London: Messi has proved time and time-again that he has the stomach for the big occasion. It's only a matter of time until he proves that again in this game.
James: This is easily the worst match in the round of 16.
Kevin, Edinburgh: This game is exactly the reason why Carlos Tevez should have been taken to the World Cup. A striker who will put the extra effort in at all times.

Switzerland are so close to taking this to extra time.
But they'll remember what Argentina did to Iran in stoppage time earlier in the tournament.
Three minutes of added time.

BBC Radio 5 live"Switzerland got demolished by France, obviously they have learned from that. Today they have been a lot more solid, if a lot less ambitious, but it is working for them. They have worked so hard. But we have seen some late goals. Including Lionel Messi's against Iran."
