Great Britain's Ben Proud has insisted that he could have raced faster after finishing eighth in the 50m butterfly final at the World Championships in Kazan.
The 20-year-old clocked a time of 23.39 seconds, while France's Florent Manaudou took gold in 22.97s.
"It wasn't my race today," Proud told BBC Sport. "It's a little disappointing. I knew the times wouldn't be as fast as last night, but it's all a learning experience. I think I could have done faster, but maybe next time."
Just 0.42 seconds separated the entire field.
