Not been but watching on TV the moments when the ball would go behind the goal (when Elliot was fetching, timewasting etc) are very odd to watch. You really get a sense of just how far away the stand is and how much space there is. As oversized as the Stadio Olimpico is (Roma will finally be starting on a new stadium soon) there is at least advertising hoardings that must be hopped and stop the ball just rolling away.
