Men's final: Brazil v Germany (tomorrow, 4.30am)
Should Neymar and Co clinch Brazil's first-ever Olympic football gold by beating Germany in the final, they will go a long way in appeasing their demanding fans after poor tournament outings in the past few years. Not to mention avenging that hideous 7-1 semi-final thrashing by the Germans at the 2014 World Cup, which they also hosted.
Women's final round (from 6pm)
The top women's golfers vie for the first women's golf gold since 1900.
