Portugal are just hanging on now. Can Chile find a winner? Between those chances and the penalty appeal, they probably deserve it now.

Oh Chile are so, so close to the final. Arturo Vidal's shot from the edge of the box hits the post, it comes back to Martin Rodriguez, who has to react quickly and he hooks it against the crossbar.

Portugal midfielder Andre Gomes rakes the back of Arturo Vidal's legs. He could have been in trouble for that but escapes - and he's immediately replaced by Gelson Martins.

Portugal's Cedric Soares has had a great game but he's exhausted and lazily brings down Alexis Sanchez. He's booked.

Well, well, well. Chile should have a penalty. Francisco Silva, who has just come on, knocks the ball past Jose Fonte, who brings him down without getting a touch of the ball.

The referee could use the video replay - and if he sees that properly, he would surely award a penalty. But he chooses not to. He hasn't used it once. Has he forgotten about it???

Bizarre.

Chile do make their second change, Francisco Silva replacing Pablo Hernandez in midfield.

Portugal defender Bruno Alves catches Pablo Hernandez with an arm. He gets booked.

Chile are allowed four substitutes. They've made one. There's 10 minutes left Juan Antonio Pizzi obviously not fancying his alternatives.

Portugal defender Eliseu is caught late on the edge of the box by Mauricio Isla, who doesn't get near the ball. The referee doesn't give him a free-kick, not sure why. Would have been a good opportunity for Cristiano Ronaldo to blaze a shot over too.

There's nothing happening really. We probably should have just gone with my coin toss suggestion.

The old quick extra-time half-time turnaround. We are under way again.

Ball is played out right to Charles Aranguiz. If he lets it run, he could be in. But, the ball hits his back. He falls over. Sums up this extra time.

And the half-time whistle goes.

One minute added on. Chile have an attack but don't make the most of it and the ball loops into Rui Patricio's hands.

The ball lands to Andre Gomes in the box and he tries to find El Clasico rival Cristiano Ronaldo but underhits the pass and Chile get it clear.

Nasir: This game can go on till eternity and it will remain 0-0

Portugal started off with three players called Silva in the team. They've all come off now. Adrien is replaced by highly experienced midfielder Joao Moutinho.

They do get a fourth sub if they want though because of new rules.

Arturo Vidal gets his head bravely onto a cross with Jose Fonte's boot close by. Fonte puts him off enough that the header isn't near goal.

We have now had ONE HUNDRED MINUTES without a goal.

Corner to Portugal as Ricardo Quaresma's cross is deflected out. It almost finds Jose Fonte, but doesn't. Ball ends up at Cristiano Ronaldo's feet and Arturo Vidal crunches him and slides it out for another corner.
