Franco Costanzo (born 5 September 1980 in Río Cuarto, Córdoba Province) is a Argentine international football goalkeeper who plays for Chilean Primera División club Universidad Católica. He has earned the reputation of being an eccentric goalkeeper by often dribbling the ball past the opposition's strikers and by making somewhat unorthodox saves. Early in his career, Costanzo was once considered an excellent prospect; however, due to a few lengthy injuries, he has only recently managed to fulfill his full potential.
