When using a 4–4–2 like that of the multichampion Estudiantes de La Plata of the 1960s or the Argentine national team that became runners-up in the 2014 World Cup, the numbers are the same as in 4–3–3, except that the box-to-box midfielder may have any number. In Argentina, the role is called doble 5 so there is not any convention as to which number it has. Also, due to the use of just two strikers, the number 11 May not be used at all.
