Caster Semenya has turned to former Olympic champion Maria Mutola to help her win gold in London next year.

Semenya, who has previously held the world title over 800m, believes that Mutola's experience will help her improve her performances.

"Maria has been my idol since I started to run," Semenya said. "After Korea I was asking Maria if she is interested in coaching me. Her answer was positive and I am very happy now."

"Maria has had a long and super successful career. She will be a great teacher for me."

Mutola won her one and only gold medal at the Olympic Games in Sydney.
