And so we will leave you.

Thanks for joining. Will we ever again see a River Plate v Boca Juniors Copa Libertadores final? Boca will certainly hope so.

Perhaps we've not even seen the last of this edition...

Until the next time!

There we have it - the gold confetti streamers explode and the sparks fly around them as River's players lift the substantial Copa Libertadores trophy.

The Superfinal is done.

Gonzalo Martinez is making his own movies now, filming with a smartphone as the trophy is prepared for the final presentation. It's pretty enormous.

The celebrations are only just starting now. The River players stand tightly packed on low stage, look to their fans and bounce. Gonzalo Martinez shouts message of love to the camera which pans away so the microphone is out of range.

River Plate's turn. Gold around their necks. Three times they were behind over these two legs before Juan Quintero's wonderful strike in extra time.

Here come Boca's players now. Only very few are happy to keep the silver medal around their neck. Wílmar Barrios is consoled. His red card of course changed the game.

There are a lot of worried and sad faces among them. The post-mortem on this match will go on for a long, long time.

The stadium has emptied quickly and only the River section remains in full.

Those Boca fans that have stayed behind are booing the referee as he and his assistants collect their medals.

Gonzalo Martinez picks up the man of the match award. Both sets of players are on the pitch.

River's players are waiting on the Madrid pitch to collect the important trophy. There it is.

Mark: These two legs have been the best games of football I've seen in ages! Brilliantly bananas! South American football at its finest!

What an incredible end to the match. A match that took so long to finally take place and went through so much on the way.

In the end, the standout moment that defined it was a footballing one: Juan Quintero's magic strike, deep into extra time.

Never will a goal have been celebrated so fiercely in Buenos Aires.

River Plate are the new champions of South America. Copa Libertadores winners 2018.

It's their fourth title.

Sensational.

Corner ball. The keeper Esteban Andrada is up again.

Boca storm forward again in these ragged final stages.

A high cross hangs in the box, it falls to Leonardo Jara. He digs out a volley and it clips the post but goes wide. Heartbreaking for Boca.

Esteban Andrada is still way off his line, playing like a sweeper, and a long River lob looking for glory misses the target.

They come again, River. Three v three. Boca's last defender appears to push his man off the ball but the ref waves play on.

ONE minute to play. Boca's nine players will throw everything at it.

Fernando Gago has had to limp off the pitch. He looks to have pulled a muscle. Boca are down to nine.

Esteban Andrada comes out to claim a long ball and just about gets away from danger.

Julian Alvarez jinks into the box as his marker trips himself up trying to challenge. His shot is tame and easy to stop.

This classic encounter just has FOUR minutes of extra time to run. Is there time?
