Sometimes you read something so stupid you just feel like smashing your head repeatedly against the nearest wall. What a load of gonads.
If UEFA had any sense, any sense at all, they should tell Porto to sod right off and fine them for making such a joke of a complaint and making a mockery of serious issues. They're clearly only doing this because they're upset that someone has dared report their fans for the monkey chanting, which obviously they don't see anything wrong with.
Can you imagine if "unsporting" chants were outlawed (whatever that even means)? It'd end up like Wimbledon tennis, with everyone having to stay silent during play and then politely applauding both sides after a good move.
