Hooliganism is alive and all too well in the world of international football. If you don't believe me, have a look at what happened in Portugal over the weekend.
A horde of angry Sporting Lisbon supporters gave new meaning to the term "Stadium of Light" on Saturday, though hardly in a way that jives with acceptable standards of public safety or even human decency.
Upset by their side's 1-0 loss to Benfica in the Lisbon derby, some boneheaded fans of the Sportinguistas decided to set fire to world-renowned stadium, referred to fondly by Benfica's supporters as "The Cathedral."
Local firefighters were able to subdue the blaze and limit the damage to just one section of the elegant venue. There's no word yet as to what sort of penalties, if any, will be leveled against Sporting Lisbon as a result of its supporters' destructive behavior.
The victory pushed the Aguias back to the top of the table in Portuguese Liga ZON Sagres, one point ahead of Porto and four clear of Sporting Lisbon.
Benfica's Javi Garcia certainly didn't start the fire, but he is responsible for the lone goal of the game that gave Benfica three points from what turned out to be a rather testy affair on the pitch as well.
Even Sir Alex Ferguson, whose Manchester United sides have struggled against Benfica at the Stadium of Light in UEFA Champions League play in the past, must be shaking his head at this news.
