It's long since proved that no one knows anything, but already these Euros have shown that our plight is even worse - and better - than originally feared. Knowing nothing is a neutral state; being wrong almost all the time is entirely different. And beautiful! Oh, us!

Half-time engagement: Not sure the sentiment is especially insightful.

Half-time: Portugal 1-0 Iceland. Sigurdsson will rue that missed early chance, but otherwise Portugal have been comfortable and menacing.

Gunnarsson blackens Nani's ankle, and there follows writhing. It's the last action of the first half.

This Portugal midfield will be a mither for any midfield in the competition, and only one midfield in the competition has Ronaldo in front of it.

The Nani goal that separates the teams at half-time.

Apparently Nani's goal was the 600th in European Championship tournament history. A hearty mazal tov to all concerned.

A lull.

Lovely break from Portugal, going through Gomes and Nani, the latter nashing out to the right-wing and wrapping his foot around an excellent cross. But before Ronaldo can connect, Halldorsson flies into its path and claims very competently indeed.

Portugal look in the mood for more here, but Iceland aren't sitting back and Sigurdsson crosses well to the bear post, looking for Sigthorsson - Carvalho is forced to concede a corner, which comes to nowt. Iceland really haven't done enough with their set-pieces.

It's blurry because he's fast...

Halldorsson has come dressed as a Chippendale.

So far, Andre Gomes of Manchester United looks a better player than Joao Mario of Manchester United.

GOAL! Portugal 1-0 Iceland (Nani 31). Simple as. Andre Gomes, at inside-right, flicks a long pass around the corner for Vieirinha, on the touchline. When the return arrives, he smacks a low cross at the near post, where Nani Greaves lurks; he loses his man and tucks a finish inside that same near post before celebrating with the self-effacement for which he is so widely loved.

Teasing ball in from Mario on the left, coming inside and curling it towards Moutinho at the near post - but it's fractionally high for him.

Pretty sure the point of this photo would elude me were it not for the emoji.

Pepe seeks Ronaldo with a delicious long pass, and the anticipation is as perfect as the execution. But Ronaldo, ahead of his man and staring out the keeper, can't control, and the ball runs away! He is useless!

Pepe and Carvalho are up there with dastardliest centre-back pairings of all-time.

Andre Gomes, at the top-right corner of the box, curves a pleasant cross towards Ronaldo at the back post; he hads over.

Wonderful wondrousness from Ronaldo, pulling to the left and twinkling over the ball inside and out before dragging it outside Skulason, coming back and clipping a perfect cross onto Nani's brow. And Nani's run is good too, between two men, and he gets good contact, but picks out Halldorsson's feet. Good save.
