Guillermo Villas: Settling the Score (2020)

For more than forty years, Argentinean sportsman Guillermo Vilas, a tennis legend, has tirelessly demanded that the official rankings (1973-78) be revised in order to finally be recognized as the best player in the world. Eduardo Puppo, an Argentinian sports journalist, and Romanian mathematician Marian Ciulpan are making Vilas' demand theirs owns, fought for more than ten years against a powerful sports corporation to prove that Vilas was indeed No. 1 in the old ATP ranking system for seven weeks between 1975 and 1976, and unfairly displaced from the top of world tennis.
