Earlier Maradona was caught pulling the fingers at opposing fans after Argentina scored a late winner.
Television cameras caught the World Cup winner reacting in the crude fashion after Marcos Rojo booked Argentina a spot in the second round with a 2-1 win - where they will face France.
Maradona is no stranger to controversy on and off the field. He is most famous for the "Hand of God" in the 1986 World Cup against England, when he used his hand to score.
Maradona led Argentina to World Cup success in 1986 and helped the side reach the final four years later.
Earlier in the game, Argentina fans broke out into spontaneous chants of "Diego! Diego" when Maradona was shown taking his seat at the St. Petersburg stadium.
Maradona briefly danced with a woman in the stands as fans took photos of him.
