Richarlison made history by becoming the first Premier League player to score a hat-trick at the Olympic Games as Brazil had to hold on to fend off a late comeback from 10-man Germany.
Andre Jardine's men got off to a brilliant start when Ajax winger Antony sent Richarlison through on goal, with the Everton star needing to cracks at goal to beat Florian Muller in net after just even minutes of play.
It took just 15 more minutes for Richarlison to get his second of the game, as he got his head onto the end of Arana's cross to leave the German defence flat-footed.
