Olympic silver medalist Caster Semenya says she is still keen to compete at this year's athletics world championships but her coach says the 800m specialist might have to consider giving up on the season.

The mixed messages from the Semenya camp came a week after the 22-year-old was removed from the list of elite athletes who are funded by South Africa's Olympic Committee because she was allegedly not training.

Semenya, laid low in recent months with left knee problems, said she had been working towards another tilt at the world title when the championships are hosted in Moscow in August.
