Grégorio Juan Esperón (known in different sources as Iván Esperón or Gregorio Esperón) (August 15, 1912 – September 30, 2000) was an Argentine professional football player and coach. He was a very good right back, probably, the best defensive player in the history of Platense. In 1938, he refused a transfer to a bigger club, because he did not want his team, Platense, to be weakened. As a player, at the end of his career, he played 7 games for A.S. Roma in the Serie A in the 1946/47 season, where he also coached the youth teams.
