We wanted to win this competition because we are huge soccer fans and because we knew that there are a few things that haven't been done, like the use of light and the use of color.

It's people only that you see, there's very little architecture that you see inside.

The people surround the pitch, under the sky or under the floodlights and that it's it. It's really like an instrument of perception. You cannot only design a building to make it beautiful. It has to really work well with the huge crowd that is using it.
