Even before the final serve in Tuesday's women's table tennis team final, China head coach Kong Linghui was thinking about the 2020 Tokyo Games.

"While Li Xiaoxia and I were watching the third doubles game on the side court, we talked about what the situation would be in four years," said Kong, who guided China to yet another gold medal.

"It definitely won't be this easy. I mean, Germany is a great team and Japan could be a much tougher opponent when Tokyo hosts the Games."
