Dartford sprinter Adam Gemili renews his rivalry with superstar Usain Bolt at the Diamond League meeting in Zurich on Thursday night.

The 19-year-old runs in the 100m against the world record holder and controversial American Justin Gatlin.

Gemili made headlines at the recent World Championships when he broke the 20-second barrier in the 200m. His time of 19.98, which came in the semi-final, was the fastest by a British athlete since John Regis almost 20 years ago.

Gemili finished fourth in the 200m final, which Bolt won, just missing out on a medal.

He looked to have made amends with a bronze in the 4x100m relay but Great Britain were later disqualified for an illegal baton handover.

Gatlin previously served a four-year ban after testing positive for a banned substance.
