Dina Asher-Smith believes she has proved her class on the global stage after setting a new British record to claim a historic 100m silver medal at the World Championships.
The 23-year-old, from Orpington, clinched second in 10.83 seconds - breaking her own national mark - to become the first British woman to win an individual world sprint medal.
Jamaica's double Olympic champion Shelly-Ann Fraser-Pryce took her fourth 100m world title in 10.71secs while the Ivory Coast's Marie-Josee Ta Lou was third.
Asher-Smith also revealed she gave up sweets ahead of the Championships and the magnitude of her achievement was quickly sinking in.
It was also Great Britain's 100th medal at the World Championships since it started in 1983.
But it was another embarrassment for the IAAF with the Khalifa International Stadium virtually empty for the final.
Asher-Smith now turns her attention to the 200m, with the heats in Doha on Monday, and she is favourite to win gold in Wednesday's final.
