Darui boldly threw at the feet of opponents in possession of the ball and drew lasting attention to himself with spectacular saves, in particular due to his unrestricted “air superiority” in the penalty area (punch defence), clearing the balls very long and very precise. He had become the game-determining figure not only in his own penalty area. He was able to organize his back team loudly (today a basic qualification for top goalkeepers, at that time still the absolute exception) and also caused moments of surprise in the game up front when he dropkicked balls that came on his goal sharply and precisely to his own attackers past the center line. With Julien Darui, the role of goalkeeper has become spectacular. This precursor profoundly upset the codes of the profession. If no natural quality predisposed him to it (he measures only 1m69), the French goalkeeper compensated with an exceptional jump and above all a certain idea of ​​the game, more than that: a real theory. Very critical of the goalkeepers (very numerous in the 1930s) glued to their line, he advocates a broader role for the keeper. He wants to make the entire area the goalkeepers' playground. His outbursts and exits have made a lasting impression. He also developed the game on foot to become an effective receiver, an active goalkeeper as he defined himself.
