I'm with adidas for almost 20 years and since 1998 I'm involved in the development and the design of the official match ball for the Fifa World Cup.

I'm a passionate footballer and that is why I'm really proud and excited to be part of these big events.

Oh! It's mixed up! So this ball goes to this position here.

What makes a good ball? The combination of many things: roundness, mass balance flight stability, texture for wet grip.

From the players point of view it's important to have a super balanced, a super uniform ball that behaves perfectly and allows him to express his skills no matter what the conditions are.

How did we achieve the Brazucas final pannel shape,

consisting of six panels?

We have looked into the mathematical world or the world of geometry,

And then we found the cube and it also consists of six identical elements of the same size.

This is a radical simplification of the ball manufacturing that leads to less defects, less potential failures to higher uniformity, to higher symetry.

That in the end produces a ball that performs perfectly.

This is our ait Test Center. This is where we have to test the balls after they have already passed the standard test procedures like the Fifa denomination test.

We have built our own specific test devices.

This is our so-called Robi-Leg, It can do straight kicks, curve kicks, all sorts of reverse spin, side spin. And we get an objective feedback. Daniel, please go ahead...

This is our second special test that we have also designed.

This machine is needed just to detect any sort of unbalance.

Here our target is to have the least amount of out-of-balance in order to make the ball fly perfectly straight.

So what I do, I take all these findings, all this knowledge, and transform it into one perfect ball concept.

Moments of goosebumps; it's always when the ball gets presented to the world.

In South Africa in 2010 when the games started, that was an absolutely, exciting, fantastic moment.

I think with this ball we have really created something exciting
