I think Carras' charge of "selection bias" is worth considering though. Selection bias plays a stronger role in the average football supporter's view of referee/UEFA/FIFA bias than anything else. While I will rail against ref's decisions with the best of them whilst watching teams I like, I honestly don't see any much evidence for conspiracy, nor support for bias due to"naturalism" (I'm really not sure that appropriating that philosophical term is the best way of explaining your point, but that's a separate matter). I accept there are exceptions - e.g. the South Korean team's progress in their home World Cup smacks of some level of bias, conscious or otherwise. Whether you are just kidding yourself and taking selected facts to support your hypothesis I can't really say, but to be fair to Carras, it is something most sports fans suffer from.
