Now ranked a lowly 52 in the world, Momota won 21-16, 21-15 against the world number 26 in the final in Gwangju.

The Korea Masters did not boast the very top players in the world but the title will be a huge boost to the 29-year-old Momota after a difficult few years.

Momota is a two-time world champion but his once brilliant career has been in freefall ever since a car crash in January 2020 in Malaysia.

The badminton ace was badly hurt and the driver of the vehicle he was travelling in killed.

He had won a record-breaking 11 titles in 2019, losing just six of the 73 matches he played and looking every inch a legend in the making.

But the crash left him with double vision and needing surgery on a bone near his eye.

His last title before Sunday was in Indonesia in November 2021.
