QUOTES OF THE DAY
"To win an Olympic medal is special. To win an Olympic medal with your wife standing next to you, taking the penalty [stroke] in the pressure moments, is so special and we will cherish this for the rest of our lives." - Great Britain's Kate Richardson-Walsh on winning gold in the women's hockey alongside her wife Helen.
"It was pathetic. Nothing Australian about it," - Joe Ingles reflects on Australia's heavy loss to Serbia in the men's basketball semi-final. Andrew Bogut added: "They [Serbia] kicked our ass from start to finish."
"When we fenced one another we'd get really aggressive." - Gold medal winner in the women's modern pentathlon, Chloe Esposito, speaking about her brother Max, who is also in Rio competing in the men's competition.
"I am going to dance and sing and it won't matter if I'm a little bit out of key." - Germany coach Silvia Neid after her side won the women's football tournament.
Cheick Sallah Cisse made history by winning Ivory Coast's first gold medal at an Olympic Games, and did so in stunning fashion.
The 23-year-old - competing in the final of the men's 80kg taekwondo division - landed his winning kick on Great Britain's Lutalo Muhammad with one second of their bout remaining.
Muhammad was leading 6-5 and looked to have the gold medal all but wrapped up, but Cisse had other ideas, spinning and delivering a three-point kick before running away towards the crowd in jubilant celebration.
Asked what he will do when he gets home, Cisse said: "I want to hug my parents, this is the first thing. And I want to hang the medal around the neck of our president."
Cisse delivered his country's maiden Olympic gold and Dilshod Nazarov did the same for Tajikistan. The 34-year-old won the final of the men's hammer, making history for the Asian nation.
"The reaction back home is going to be hard to imagine. I've got hundreds, maybe thousands of 'likes' on my Facebook account, so I think the country were behind me tonight," Nazarov said.
Hosts Brazil face Germany in the final of the men's football tournament on Saturday, with Neymar and Co. looking to secure their nation's first title in the competition.
