CCTV5 will definitely broadcast the Champions League live, because since the beginning of this season, CCTV5 has bought out the exclusive rights to broadcast the Champions League in Chinese mainland for the next three years.
Europe and America have a time zone of 4-5 hours. If there is a China athlete competition in February 17/2. 18 (generally at 20: 45 European time, while American time happens to be in the evening), I think CCTV 5 will definitely broadcast the Winter Olympics.
