#6 Showing the finger
This one is among the recent ones. Argentina needed a win against Nigeria to qualify for the round of 16. While the Argentine players were giving their all on the pitch, Maradona was backing them from the stands.
All great.
Then Messi scores and Maradona goes berserk, almost as though he has been possessed by a djinn.
Nigeria equalized and he was visibly upset. After a while, he was caught sleeping on camera – and it was later revealed that he needed medical attention.
Finally, when Marcos Rojo scored a peach of a goal in the final few minutes of the game, the Argentina legend was visibly out of control and showed the middle finger of both his hands while celebrating.
On live TV. During a World Cup game. Wow.
