Chinese badminton superstar Lin Dan, a two-time Olympic champion, has accused his Super League club of failing to pay him and six others for the 2016-17 season.

Regarded by some as badminton's all-time greatest player, Lin said he was "bitterly disappointed" and threatened to take legal action because, he said, Guangzhou Yueyu badminton club failed to pay.

Lin said the players worked the whole season to keep the club from being relegated despite not getting their wages.
