(CNN) -- Usain Bolt bids to become the first man to win the Olympic sprint double twice while World Cup champ Japan seeks to win a second major soccer title. Here are five things to watch at the Olympics on Thursday: 1) Men's 200 meters: Jamaica vs. Jamaica Before you go giving Bolt the gold medal, Yohan Blake has something he wants to say. "I'm not really focusing on beating him. I'm concentrating on running my race. My plan is just to execute," says the Jamaican champion. Wallace Spearmon of the United States will try to spoil the race, but after Blake and Bolt looked so impressive in their heats, it's hard to see anyone challenging the training partners and friends.
