The second leg of the Copa Libertadores final between fierce rivals Boca Juniors and River Plate was never going to pass by incident free.In what is South America’s equivalent of the Champions League final, the neighbours from Buenos Aires were tied at 2-2 following last weekend’s thrilling first leg at the Bombonera.The second leg was due to take place at River’s famous El Monumental stadium on Saturday evening - but there were shameful scenes before kick-off outside the stadium and the match was subsequently delayed by an hour. Many people felt it should have been postponed.River fans pelted the Boca team bus with stones and other objects as it made its way through the streets. According to Spanish newspaper AS, this resulted in players on the bus being injured.Several Boca players - including Carlos Tevez - were also reportedly affected by tear gas that had been sprayed by police in order to clear the crowds.Per the Independent’s Miguel Delaney, there were reports that three Boca players were taken to hospital following the incident, with Pablo Perez hospitalised after glass had gone into his eye.Boca players had asked CONMEBOL doctors to examine their players, amid reports that several of them were in no condition to play in the Superclasico.

The presidents of both River and Boca met to discuss what to do and, shortly afterwards, news filtered through that the game was going ahead despite the terrible scenes.

Footage showed some of the damage that has been caused inside the bus…

Meanwhile, other footage was shared online - courtesy of Argentina’s Marca - of a River fan attempting to sneak flares into the stadium by attaching them to a young girl.

Here’s the footage, filmed by somebody in a car at the scene…

Needless to say, the video has led to widespread condemnation - and rightly so.

It’s been shared by many shocked football fans around the world, including the former Bolton Wanderers and United States midfielder Stuart Holden.

We’re all for passion in football - but, sadly, many lines have been crossed ahead of what should have been an occasion to remember for all the right reasons.
