The much-anticipated clash between the Americans and Canada, which will begin 9 pm local time, will take center-stage, with the US looking to avenge that epic final loss in the last Olympics. Canada will probably start as the slight favorite, but USA have shown this tournament they have the quality to rip apart any side.

"I think both teams are really evenly matched," said USA's Drew Doughty. "I don't know who I would give the upper hand to at this point. But I'm obviously more confident in my team than theirs. I'm just really looking forward to it. It's going to be a huge game."   

Elsewhere, Canada's Marielle Thompson starts off as favourite in freestyle skiing with two ladies from Switzerland - Fanny Smith and Katrin Mueller. In Alpine skiing, on the other hand, America's Mikaela Shiffrin is a leading medal contender. Shiffrin, called the Mozart of skiing, is only 18 years old and will be the youngest in Olympic history to claim gold medal in this event, if she manages to get to the top step of the podium.

The women have done the trick for Canada by winning their country a gold medal, now all eyes ae on their men counterparts to do the same as they face Britain in the men's curling finals. China and Sweden will fight for bronze in the same event.

In long-track speedskating, Dutch men start as favourites in the 5,000 meter relay while it's athletes from Russia who stand ahead as front runners in the short track 500 meter section. The women's 1000 meters relay looks to be an all South Korea affair, although Italy's Arianna Fontana has also come good in recent times.

The ladies from Norway and Canada have shown to be ahead in the run when it comes to biathlon team relay. However, Russia is also ahead in the medal contention.

Norway is in the lead of the medals tally with ten gold medals as on February 20, 2014 after close of play, with US and Germany right behind on eight gold each.
