-- Forward to @01:20 if you cant wait to see the action --

Last thursday night’s Europa League match between Athletic Bilbao-Anderlecht was marred as hundreds of rivals supporters spilled out onto the field after the full-time whistle was blown to engage in fisty-cuffs.

Prior to the match five Belgians and a Spaniard were detained between clashes for destroying pubs and properties near the stadium.

Some Bilbao and Anderlecht supporters invaded the pitch after the match, causing a violent riot amongst the fans, whereas other Basque fans engaged in a discussion with the Belgian visitors in the stands and two of these aficionados went a bit further, than the "usual."

Above the visiting fans, one of the Basques was throwing plastic cups at the opposing fans, whilst another fan decided to, literally, urinate on the Belgian fans.

The whole scene was caught by TV cameras and Athletic Bilbao's board promptly identified the subject as one of the many affiliated fans. His membership was suspended for an indefinite period of time.

Some say the Basques fans were provocated when the Belgians fans started to chant "Viva La Espana!". As everyone knows Bilbao fans are very proud of their identity.

The Athletic Bilbao unique philosophy of only incorporating players native to the Basque region - that's born in or with Basque parents - has effectively meant that it has been an all-white bastion until last December, when Ramalho was the first black player to play for Bilbao.

The clubs themselves are now waiting to see whether they’ll face heavy sanctions from UEFA due to their responsibility in the crowd trouble.
