The refereeing decisions are no different to what we see and complain about in the PL week after week.
Chelsea losing at home to West Brom, Ramires goes in and falls, penalty. Given immediately. Protests from WBA players, yellow cards given out, goal scored. Phew. Everyone relieved.
Arsenal losing at home to, say, Norwich. Need a goal, desperately. Player falls, penalty. 1-1. Then Arsenal score twice more in the next ten minutes through their own good play.
Brazil's 3rd goal was very well taken. The damage is done in the 2nd goal, which is then followed up by a challenge, if you can call it that, on the keeper which is given.
It's the same weak officiating from people who are either not up to the task or instructed to give these decisions. The Japanese ref isn't even one of Asia's best, the standard of refereeing in the Asian CL is terrible, there is a heavy Brazilian influence in the J-League... so why choose a sub-par Japanese ref for the opening game when all eyes are on Sao Paulo? surely it will only ever suit the hosts. The deferential attitude towards green and gold, the home crowd pressure, the expectation, and the underlying need to pacify an anti-world cup (spending, not tournament) public.
You just know that decision would not be given to Croatia. There was an opportunity for Fred to dive/ref to give in and it was taken. A reminder that a football match is not just two teams of 11. Sad.
