Fittingly, the ball has the same blue and white colours as tournament hosts Israel and its design features the same thermally bonded triangular patterns as the adidas Tango 12, match ball of UEFA EURO 2012.Avi Nimni added: "The ball is very light and easy to control and I hope we will see a lot of goals in the tournament."adidas has produced the official ball for every major UEFA and FIFA tournament since 1970.
