Diego Maradona
In the 1984 Copa Del Rey final against Athletic Bilbao, Maradona was involved in a fight with several other Bilbao players. During the game, Bilbao player Andoni Goikoetxea made a rough tackle on Maradona, and Bilbao fans insulted Maradona and his family. This made him very angry. Barca lost 1-0, and when he was insulted by Miguel Sola at the end of the match, Maradona lost control and became furious. He headbutted Sola, kneed Bilbao's goalie in the head, elbowed another one in the face, and kicked and punched other players as well. This ended up being his last game with the Catalan club.
