Before the games started I would have said USA to continue at the top of the gold medal table.
Now even just 1 day into it China has already taken some 'unexpected' golds'
Even in those events where China has not previously figured, they look top top quality.
China has been developing it's sports teams to extraordinary levels now for more than 3 Olympic Games.
All part of their world domination
Personally I expect China to pip USA this year.
