It was a night to remember at the Rio Olympics as Usain Bolt won his third consecutive 100m gold medal, but the show was stolen by a lesser-known figure.
South African Wayde van Niekerk was the man of the moment as he smashed Michael Johnson's 17-year-old record in the 400m, running the lap in a stunning 43.03s.
Johnson's record was set way back in 1999, with the American registering a time of 43.18s, but that record has now been passed onto Van Niekerk, who won a share of admirers overnight due to his incredible performance.
