CTRUS. A football—as in soccer—that doesn’t use air but an inner elastic structure and an elastomer skin that perfectly simulates a real football. It’s also the ball that would avoid many referee mistakes.

Many people argue that one of the beauties of soccer is the occasional mistakes made by referees, specially the offsides. But when it’s your team that gets eliminated from a World Cup or the UEFA Champions League because of one of those mistakes, it’s not funny at all. And it may cost your club millions of pounds.
