Sun Tzu
Getting enough top class officials is an ongoing problem, and refs have always been criticised / blamed and will always get this. They make mistakes, they get things wrong, they have bad days. But what is your great solution ?
The School for Officiating Excellence... a university just for referees and linesmen where people actually just go and spend a couple of years of their life to get a degree in refereeing by officiating a mixture of real life games and virtual games and situations in a simulator, where if they get the decision wrong they get electrocuted or Craig Bellamy beats you up with a golf club.
Or a Centre for Refereeing Development - basically a place where genetically engineered humans will be created with super senses and eyes in the back of their heads... the X-Refs...
Meanwhile, in the real world I don't loathe Pearce, I just don't think that he's as good as they made out he was going to be.
