Already the most decorated Olympian in history, Phelps has now won more medals than many countries. Team US – who are currently dominating Rio 2016 – turned out in force to watch the swimmer snatch his 20th gold medal in the 200m butterfly.

Members of the men’s basketball team were caught on camera cheering wildly as Phelps, 31, stormed to victory ahead of his rival Chad le Clos. Footage of Draymond Green, Kevin Durant, Deandre Jordan, DeMarcus Cousins and Klay Thompson celebrating their teammate’s win has been a hit online, with Twitter users praising their enthusiasm. WHY DOES PHELPS HAVE BIG RED CIRCLES ALL OVER HIS BODY?

“The US men's basketball team wins best cheerleaders,” wrote Sierra Sachtjen. While Austin Nichols said watching the players was “the best thing about the Olympics tonight”. One fan pointed out: “If Michael Phelps gives every member of the US basketball team a gold medal, he can still wear six around his neck and use two for coasters.” BASKETBALL PLAYERS FLY THROUGH THE AIR AT RIO 2016

Phelps’s victory was all the more poignant as he had lost the same event to Le Clos at London 2012, which was supposed to be the American’s Olympic farewell. He came out of retirement to compete in Rio, telling his coach Bob Bowman “he badly wanted that 200m fly”. Relations between the Phelps and Le Clos have been tense throughout the Games. WHEN IS PHELPS RACING?
