I&rsquom sitting in the Turkish Airlines box in the Camp Nou, Europe&rsquos largest football stadium, watching FC Barcelona take on Celtic FC in the group stage of the world&rsquos greatest football competition, the UEFA Champions League. In the adjoining box, sits a visibly pregnant and elated pop singer Shakira she&rsquos doing a different kind of a belly-dance for the amusement of her friends. And I&rsquom undergoing deep thoughts over the direction of the sport.
