Of courses its bogus.
Zidane got the question of the most amazing thing he aver seen on a pitch was. The answer: Maradona hitting the post 5 times in a row on warmup before a game. The reporter asked Zidane if he could try and he did not hit it once.
Nike heard of this and made a commerial out of it.
But that proves once and for all that maradona was something else.
Another Maradona story.
Glenn Stromberg, playing for Bolonga liked to warm up by himself before matches. Went down under the pitch with a ball when they plyed away against Napoli. Down there in the garage was Maradona all alone playing. He was joggling the ball around a pole. Hitting it and crving it around the pole with his left, did the same with his right and just kept curving it around the pole to himself. Glenn just walked away...
True story, heard Glenn himself tell the story.
