You can try to explain how it was a judgement call, but that doesn't mean it was. It was a pure gift from Fifa, and it was complete bullshit. There was nothing that looked remotely close to a foul and the the official pointed for the penalty without hesitation as if he was told to call it. Sorry, there's no explaining that. Just pure garbage for the host nation...
I've been watching EPL for years and this kind of crap never gets called. Ref was looking for a chance to call a penalty and Fred with terrible acting job was just that. Croatia played clean, physical soccer and Brazil fuging stunk.
On top of that... The 2nd goal Croatia scored was not a fault, Cesar missed the ball and it hit Olic directly in the head. Refs blew the whistle without hesitation. Cesar was on the ground with goal wide open.
Croatia got rapped by FIFA.
The way FIFA is working, Qatar will win World Cup in 2022.
