Each week we publish a gallery of readers' pictures on a set theme. This week the theme is football and we begin with a photograph taken by Michael Currin of a practice session at the University of Cape Town.

Andy Parker: "These young Italians in Venice use one of the city's small piazzas as a pitch and the archway of a nearby church as a goal to compensate for the lack of green space."
