Eighteen-year-old sprinter Adam Gemili may skip the Olympics for fear competing at the Games may harm his development.
Gemili ran a time of 10.08 seconds at the Sparkassen Gala in Regensburg, Germany this weekend, putting him at the top of the British rankings and securing the Olympic A standard.
But his coach Michael Afilaka said Gemili was still aiming for the World Junior Championships in Barcelona in July rather than the London Games.
Competing in both as it stands presents some difficulty as the trials are less than a week apart.
Afilaka told the Daily Telegraph: "If there is leeway to get us to the Olympics we'll consider it, but right now the aim is stick to going to the World Juniors."
He added: "The management of our junior guys is something I've been really concerned about. We don't manage them very well and we do too much too soon."
Gemili, a former footballer who spent time in Chelsea's youth set-up, has seen dramatic improvements since choosing to concentrate on athletics earlier this year.
And the teenager seemed keener than his coach on competing in London.
"My focus so far has been the World Juniors but following this my coach and I will definitely be sitting down to discuss options," he said in the Telegraph. "It's a great opportunity and a nice dilemma to have."
