"Logo of FIFA World Cup 2014 is a nightmare"

An American designer named Felix Sockwell. He is art director and accumulated experience in major advertising agencies like DDB, The Richards Group and Ogilvy. He saw the logo produced for the 2014 FIFA World Cup in Brazil a nightmare.
He said there are several points that need improvement in the brand so that it becomes a more professional brand, as you can see here on his blog (in English) or here on UOL Esportes (in Portuguese).
