Great Britain's Jade Jones has failed to scoop her first ever Taekwondo Grand Prix gold medal following defeat to Spain's Eva Calvo Gomez in Manchester.
The 21-year-old came close to glory after tying the -57kg final 4-4, but eventually lost to the world number one, who has beaten Jones three times.
"It's frustrating," Jones told BBC Sport. "I've made improvements but I need to go back to the drawing board."
Both Jones and Britain's Aaron Cook took home silver medals.
