Up, up, up they go. Those big orange balloons. Into the evening sky. We weren't sure then and we're still not sure now why they were released. Perhaps some sort of celebration of the new season, like smashing a bottle on a new boat. They'll most likely wash up on Barceloneta beach in a few days time. Either that or some sealife will wash ashore with orange latex stuck in its throat. Still, the Messi masterclass that unfolded below - preseason game or not - proved even more of a spectacle, as the sun set over Catalunya's capital.
