#7 Messi tax evasion
And we conclude our slide with the best player in the history of the game. He might be the best ever, and do things with a football that none else could even dream of. However, when it comes to managing his taxes, he is as clueless as Bambi on ice.
And it is for this reason that someone like him had to see his name get tarnished because of this. As he was busy playing football, he made the mistake of not reading tax papers and signing on them. Sometimes, blind trust can lead to disaster and that is what happened with the Argentine.
He has had such a glorious career that people might not even remember this incident once he is done with the game. However, it is a tiny black spot that he can never hide.
