Athletic Bilbao is a club known for its strict roster rules, only Basque players are allowed to play for this popular team, and for its passionate fans.
During their last European fixture against Anderlecht, Athletic's fans enforced this reputation, but maybe they enforced it a little too much.
According to most newspapers, Anderlecht fans started to mess around with the Basque supporters, thus breaking the golden rule of Spanish football: You should never provoke an angry horde of Athletic fans. It has the same effect as dancing in front of a bull with a red cape.
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."
Sitting 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.
Some dare to call him genius, others call him simply a drunk buffoon, but everyone knows him as "el orinador" (Spanish for "The Urinater").
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.
Most likely, this Basque fan will be kept out of San Mamés (Bilbao's stadium) for some years, which is quite a shame, if I might add.
Nonetheless, this poor supporter was not the only one who was satisfying his needs in improper spots. During one of their practice sessions two Anderlecht players decided to urinate near the stands. Now I can understand why the Manneken Piss is Brussel's most famous monument.
