Russia takes center stage in the sporting year 2018 as host of the football World Cup while its athletes at the Winter Olympics must keep a low profile.
The Russian doping program issue has led to Russia's suspension from the Feb. 9 to Feb. 25 showcase in Pyeongchang, South Korea, which are the first Games on snow and ice in mainland Asia. But some 200 Russians could compete as neutral athletes with their national symbols, and the International Olympic Committee is not ruling out allowing the Russian flag back at the closing ceremony.
"Our athletes should go to South Korea and win for the glory of Russia," Russian Olympic Committee chief Alexander Zhukov said when the decision was reached to go despite the International Olympics Committee (IOC) sanctions.
Potential stars in South Korea include American skiing sensation Mikaela Shiffrin, while Nigeria seems poised to have a women's bobsled team taking part.
Apart from the Russia issue the Games take place against the backdrop of tensions on the Korean peninsula surrounding North Korea's nuclear and missile programs; and amid slow ticket sales in the host nation.
Ticket sales are much better for the football World Cup, but the doping issue also simmers there as the ruling body FIFA sees no reason to question the role of chief organizer Vitaly Mutko, who has been banned for life from the Olympics by the IOC.
In addition, investigator Richard McLaren has suggested that the Russian institutional doping program also affected footballers, possibly including national team players. FIFA is yet to take action against anyone.
The home team will mainly hope to get through the group stage while the favorites at the June 14-15 tournament include titleholders Germany, France and record winners Brazil.
The draw provided no group of death and Germany coach Joachim Loew is optimistic of advancing past Mexico, Sweden and South Korea. "It's a very interesting group from a sporting point of view. We want to lay the foundation in the group for a successful title defense," he said.
