What they dont realise is that the ball is adidas's fault, they told the designers at loughborough which specifications they wanted i.e. aerodynamics, roundness ect. The designers the made the best ball they could to meet these specifications after testing it with kicking machines, wind tunnels ect. It was then manufactuared in Germany.
In theory it is the highest quality ball ever made, however it is so affected by conditions it is hard to get used to playing with.
If it is kicked the right way it could do amazing things, I imagine that later on in the tournament we will see some spectacular goals
