Juan Evaristo has hailed as the inventor of the marianella – the volleyed backheel, Pablo Bartolucci of the diving header, and Pedro Calomino of the bicycle kick, although this last example is disputed. Some say the bicycle kick was invented in Peru in the late nineteenth century; most seem to credit Ramón Unzaga Asla, a native of Bilbao who emigrated to Chile and first used it in 1914 (hence the use of term chilena throughout Spanish-speaking South America, although it might refer to David Arellano, a Chilean who popularized the technique on a tour of Spain in 1920), while others follow Leônidas, the Brazilian forward of the thirties, in attributing it to Petronilho de Brito. Weirdly, the former Aston Villa chairman Doug Ellis also claimed to have invented the bicycle kick, even though he never played soccer to any level and was not born until ten years after the first record of Unzaga performing the trick.

Sendo menos injusto: avião é mais intelectualmente detalhado do que gol de bicicleta (no sentido de que você precisa de um pouco mais de estudo para inventar), embora o último seja igualmente maravilhoso. Não é difícil imaginar tanta gente inventando ao mesmo tempo, ainda mais nos tempos em que a comunicação global era mais lenta e escassa.
