Second ticking away now...

Poor, so poor from Ricardo Quaresma, whose free-kick fails to clear the first man and Iceland clear.

One minute to play.

Ricardo Quaresma stands over the free-kick...

Iceland have all 11 players deep in their own half, but goalscorer Birkir Bjarnason blocks Nani to concede a free-kick...

Time-wasting change from Iceland. Excellent game management.

Charlton's Johann Berg Gudmundsson off, Elmar Bjarnson on.

THREE added minutes to play.

Raphael Guerreiro's corner is headed away by the Iceland defence. They're going to hold on here.

Cristiano Ronaldo is frustrated after the ref rules he has fouled the goalkeeper.

Mr Shuffles: Really?! That was his best chance of the half. And he is meant to be the best player in the world.

Big Gray: Ronaldo with a tame header going for goal. Was more like a back pass.

dabombshell7: I so want Iceland to win this.

Portugal still pushing for the winner and earn a corner...

Three minutes remaining, who can make themselves the hero of a nation?

"Going forward, Portugal are good. But to win a tournament? I don't think their back four's up to it."

Iceland come close to a shock result.

Alfred Finnbogason's menacing left-footed strike from inside the area is arrowing towards the roof of the net, but Rui Patricio sticks both fists up to keep the ball out.

"Cristiano Ronaldo didn't really punch it as hard as he should. It was a really lovely ball in from Nani - he really should have scored."

Nope, not happening for Ronnie.

Nani whips in a beautiful cross from the right and Cristiano Ronaldo is free inside the box. He has the whole goal to aim at with his header, but can only nod straight at Hannes Halldorsson.

At the other end...

Richard: Portugal building now. Can see them getting a winner in the last 5 as fatigue starts to set in. 

Daniel Pashley: Those Icelanders are chanting "Áfram Ísland", in case you were wondering. 

Pav: Ronaldo's getting more and more frustrated by the minute.

Iceland sub Alfred Finnbogason on the ball for the first time in the Portugal penalty area, but he is sheparded out of play by Pepe.

Last change for Portugal, who send on striker Eder for midfielder Andre Gomes.

Portugal's 20 shots is the most by a team at Euro 2016 so far, only one goal to show for it through.

Can they find the winner?

Cristiano Ronaldo drills in the free-kick which comes off an Iceland defender and away for a corner.

Defender Pepe leaps to flick on Ricardo Quaresma's corner, but it hits the roof of the net.

Iceland can breathe again. They've got eight minutes left for a famous point.

Right, Cristiano Ronaldo over a free-kick. It's at least 40 yards out...

Watch the moment Nani glances a header wide from a free-kick. One of those where you can't believe it has not gone in. 

Iceland have done an excellent job since grabbing the equaliser.

They make a change as striker Alfred Finnbogason comes on for number nine Kolbeinn Sigthorsson.

Come on then Alfie, let's see what you got.

Ten minutes remaining.
