Russia's 'foreign legion' finally marches to medals

After years of making little impact on Russia's sporting fortunes, foreign-born athletes poached from abroad are finally making an impact at the Winter Olympics.

Russia has been much criticized at the Sochi Games for allowing talent to slip the net, with several athletes who were born or brought up in Russia winning gold for other countries.

But the reverse has also come true over the past few days which have seen a South Korean-born short track skater win a historic gold for Russia, a Ukrainian-born pairs skater win double gold and another Ukrainian-born short track skater win silver.
