The Tango 12 is, according to adidas, "based on the classic Tango design used during both the FIFA World Cup and UEFA Euro tournaments during the early 1980s."
It has been been developed over a two-year period, and has been rigorously tested by professional players across eight different countries.
Adidas CEO Herbert Hainer said: “The adidas Tango 12 is a combination of many years of football tradition coupled with extensive player and lab testing to make it the most tested ball adidas has ever produced.”
