Otto Siffling was one of the most talented center forwards of the 1930s. An opinionated and exceptionally gifted player, Siffling was a virtuoso on the pitch who impressed with his ingenuity and imagination when on the ball. Being not keen on overly physical play, he was not a traditional center forward, preferring to create more than to score.Taciturn in nature, he did not like to be in the spotlight and ovations at times made him feel uncomfortable.In 1938 his level suddenly dropped inexplicably, so that he was not starting in the 1938 World Cup. A year later he died of a pleurisy aged 27.
