Just in case anyone was wondering if Michael Phelps has still got it, the champion swimmer just won another gold medal at the 2016 Olympics in Rio de Janeiro, Brazil — bringing his grand total to a historic 20 Olympic gold medals.

Phelps didn't have the lead from the start of the men's 200m butterfly race, but powered through thanks to a fantastic final turn that helped push him into a first place lead. As soon as the race was over, Phelps looked extremely pleased to have come out on top. Perhaps this had something to do with the fact that he defeated Chad le Clos, an Olympic swimmer from South Africa. Phelps and le Clos' rivalry has played out in the public eye for almost two years now and this race felt like a culmination of sorts.

Le Clos won the 200m butterfly race in 2012, taking the title away from Phelps, who had won it in 2004 and 2008. Le Clos beat Phelps by just .05 seconds at the London 2012 Olympics. This time, Phelps got the victory in 1:53.36. 

Twitter users were quick to comment on the rivalry in the aftermath of this race, which ultimately ended in victory for Phelps.

Michael Phelps proved once again that he's the greatest swimmer in the world, so much so that even the team USA basketball team was squealing with excitement. Just look at Kevin Durant's face, he's positively giddy!
