Six things you missed overnight
1. Michael Phelps wins his 20th and 21st Olympic gold medals
The American - already by a distance the most decorated Olympian of all time - stormed to 200m butterfly victory and held off the challenge of South African Chad le Clos, who could only finish fourth.
Less than an hour later - after shedding tears on the podium while being awarded his 20th Olympic gold medal - Phelps anchored the USA to 4x200m freestyle relay glory.
