Barefoot goal

The Brazilian Leonidas Da Silva entered the history of football when in the 1938 World Cup against Poland he scored a goal of "barefoot".
Her boot was ruined, and since there was no other reserve, she threw her out of the field for someone from the bank to try to repair, thus leaving with one foot barefoot.
However there was a foul against Poland. Hércules, Brazil forward scored the deficit with force. The ball bounced off the post to Leónidas. The ball bounced free-kick. The referee validated the goal that is still historic today. At the moment this would not be possible, since the rules penalize as lacking any touch in the ball without boot.
