On this week's show we focus on the Rio Olympics. The women's football tournament starts on Wednesday, and the men's competition on Thursday. What can we expect from the African teams in Rio? Can Nigeria win men's gold for a second time? We continue discover the culture of Brazil, this week we go to the world-famous Copacabana beach. And while there are so many hopes of winning Olympic gold and gaining sporting fame and fortune, we ask where does true identity come from? We talk to Liverpool legend John Barnes and Zambia international Jacob Mulenga.
