Bianca Walkden says World Championship win is 'unbelievable'

Bianca Walkden says her gold medal at the World Taekwondo Championships is "unbelievable" and "a dream".

The 23-year-old Liverpudlian secured the title in the +73kg category with a thrilling late comeback victory over France's Gwladys Epangue, 31, in Chelyabinsk, Russia.

Last year, Walkden won +73kg gold in the European Championships in Baku but this is her first medal at world level.
