Diego Maradona is not given to measured pronouncements on major figures. If he likes you (Fidel Castro) he really likes you, if he doesn't like you (George W Bush), he will express that dislike in very strident terms. Stridency is the one constant.
Louis Van Gaal is not George W Bush. But Diego was in Bogota to promote a charity match and answer some questions and he was asked to comment on the travails of the golden boy Falcao.
Diego does not like the way Louis Van Gaal is handling Rademal Falcao and he does not like Louis Van Gaal.
Van Gaal is not a nice guy. Van Gaal is closer to the devil than anything.
Maradona went on to express his low opinion of Sepp Blatter, who he suggested needs a metaphorical 'kick in the backside' at the very least. His comparison of Van Gaal with the devil can't compare with his description of George Bush as 'human garbage'.
