David Jarvis: I've never seen so many two footed challenges. And in have no idea why there was an indirect free kick, I've never been this baffled watching football... it's a great watch though!

BBC World at the Bernabeu

The stadium announcer tells us there are 72,000 fans in the Santiago Bernabeu. But both sets of fans have stopped bouncing up and down behind the goals. Could they handle penalties?

Extra time it is.

The score is 3-3 on aggregate. There's no away goals.

The ref conducts a drop ball and Boca boom it back up to their rivals.

How much longer will we play?

Nahitan Nandez is still down and the ref is calling for a stretcher now.

Carlos Tevez is watching on from the sidelines. Both teams are allowed a fourth substitute in extra-time.

Ooof. That's not a convincing punch from the Boca keeper.

River recycle possession and, with a Boca player on the turf, the ref decides to call it back and stop play.

Nahitan Nandez is the man suffering, from cramp it looks like.

Boca launch a deep free-kick into the River box and there is a moment's nervous hesitation before Franco Armani finally comes to claim in front of Cristian Pavon, lurking at the far post.

THREE minutes of added time. Then we go to extra-time. And then a replay (only joking, it would pens).

Carlos Izquierdoz smashes the ball out of play. Into added time we go.

Here's Fernando Gago. Pablo Perez leaves the turf and hands over the captain's armband, but only after throwing it violently to the ground.

TWO minutes to play. Fernando Gago is going to come on soon.

Wilmar Barrios just grabs hold of his man and hauls him to the turf. Why? He wasn't even breaking clear. Yellow card for the Boca player.

Ramon Abila smashes a volley way over the bar from 30 yards. A terrible effort and bad decision to shoot from there.

River zoom up the park and almost thread a pass beyond Boca's last man.

Five minutes to play - what a time this would be for a winning goal. Nerves are frayed now. Legs are tired.

Carlos Izquierdoz digs a River cross clear of the Boca back-line.

Boca have the ball in the corner but it runs loose and River turn it over.

SIX minutes of normal time to play. Boca camped deep in their own half as River probe.

Seven minutes to run. They will go fast.

Boca look to break quickly down the left wing through Cristian Pavon but a River boot clears.

Jonatan Maidana gets a yellow card for a slide through Ramon Abila.

This is really beginning to run out of the ref's control a touch now.

Ignacio Fernandez gets a yellow card for a 50-50 collision with Ramon Abila.

Sebastian Villa loops the free-kick over the bar.

The River wall is lined up. Boca look to square this off to a free man on the edge of the box.

The referee blows for it to be taken but still Boca delay.

Lucas Olaza eventually drives a strike straight into the wall.

Still the debate goes on - the referee has been surrounded by players from both sides for the past two minutes.

It is an indirect free-kick - and not a penalty - that much we know.

This is quite odd...

Boca's Nahitan Nandez goes down in the River box and the Boca players want a penalty.

The referee has instead blown up for an indirect free-kick. I am at a total loss as to why...
