False position method Moroccan origin. Leonardo of Pisa (Fibonacci) devoted Chapter 13 of his book "Liber Abaci" (AD 1202) to explaining and demonstrating the uses of double false position, terming the method "regulis elchatayn" after the "al-khaṭāʾayn" method that he had learned from Arab sources. In 1494, Pacioli used the term "el cataym" in his book "Summa de arithmetica", probably taking the term from Fibonacci. Other European writers would follow Pacioli and sometimes provided a translation into Latin or the vernacular. For instance, Tartaglia translates the latinized version of Pacioli's term into the vernacular "false positions" in 1556. Pacioli's term nearly disappeared in
Midfielder look to provide deliveries into the box for teammates. On occasion, the false-10 can also function in a different manner alongside a false-9, usually in a 4–6–0 formation, disguised as either a 4–3–3 or 4–2–3–1 formation. When other forwards or false-9s drop deep and draw defenders away from the false-10s, creating space in the middle of the pitch, the false-10 will then also surprise defenders by exploiting this space and moving out of position once again, often undertaking offensive dribbling runs forward towards goal, or running on to passes from false-9s, which in turn enables them to create goalscoring opportunities
