The Kremlin on Friday responded to comments by the Olympic chief, in which he said he was "disturbed" watching Russian teen skater Kamila Valieva crumble under pressure and hit out at the 15-year-old's coach for her "chilling" reaction.

In a news conference earlier on Friday, International Olympic Committee president Thomas Bach said he had been "disturbed" watching Valieva's error-filled fourth place performance in the women's single Thursday night.

Bach also said he was confounded by her coach's harsh reaction afterward and called for governments to look into the role of entourages around young athletes.
