It has been a funny Olympics so far. The host nation don't seem to be dominating at any of the sports and struggling to win the medals. The favourites for different sports have been showing indifferent form at this Games, when they should be peaking at the right time to win the honours. Suddenly you see Phelps being squeeze out on medals, beaten by Lochte, USA beaten in swimming relays, Spain down and out of football, World Champions Argentina beaten in women's hockey. Don't be surprised that Usain Bolt and Yohan Blake being beaten by unknowns in the 100m sprint in athletics.
