Eighteen-year-old sprinter Adam Gemili admitted he struggled to contain his excitement after his stunning breakthrough run of 10.08 seconds lifted him to the top of the British rankings.
Gemili, a promising footballer who was a member of the Dagenham and Redbridge Academy squad last season, achieved the Olympic A standard twice at the Sparkassen Gala in Regensburg, Germany, on Saturday, running 10.11secs in the heats before going even quicker to win the final.
"When I crossed the line in 10.08 it was the most amazing feeling in the world," the Blackheath and Bromley athlete said. "When I ran my heat and saw I'd ran 10.11 I jumped into the air whilst I was still slowing down. The physios told me to calm it down else I'd end up injuring myself. So I was a bit calmer after the .08 but it was still the best feeling ever."
The Londoner, who smashed his previous personal best of 10.23s, also became the second fastest British junior of all time.
His time lifted him above Mark Lewis-Francis, a former world junior champion, on the Great Britain junior all-time list, with only Chambers' 10.06 set back in 1997 ahead of him.
Gemili trains under Michael Afilaka, who also coaches former world indoor silver medallist and 2008 Olympic finalist Jeanette Kwakye.
"Training with Michael and his group, I've learned so much from him and the whole group are brilliant," he said.
"Jeanette Kwakye is brilliant as a training partner but also as a role model, having been to an Olympic final and having a world medal. It's just been such an eye-opener."
Gemili, who won silver at last year's European Junior Championships in Estonia, is the second Briton to achieve the A standard of 10.18 this year after James Dasaolu, meaning the likes of Chambers could have their work cut out to make the team.
Dasaolu, 24, ran exactly 10.18 in France last month.
