Kim Yuna: "I get nervous all the time"

Defending women's figure skating champion Kim Yuna has admitted that she suffers from nerves during competition.

The South Korean leads the competition in Sochi following today's short programme.

The 23-year-old told reporters: "I am a human being. I get nervous all the time. It just doesn't show on my face.

"I tried to believe in myself and remember my practices. I thought if I do well in practice, I can do well in the main event."

Kim holds the world record for most points in the short, free and combined programmes.
