The top-10 of Men's singles category remains unchanged in the latest badminton rankings, which was released on 2 February with Malaysian giant Lee Chong Wei leading the pack. India's PV Sindhu has moved three spots in the Women's singles rankings, which has Taiwan's Tai Tzu Ying at the top.

Lee, the three-time Olympic silver medallist, has not played an international match since BWF Dubai World Superseries Finals 2016 and also did not defend his title at the Malaysia Masters, which was held between 17 and 22 January. The 34-year-old, who has been quite vocal about retirement and plans for future in the recent past, will begin the season at All England Championships in March.

Denmark's Jan O Jorgensen, who finished the 2016 season with a title at China Open, tails Lee at the second spot while compatriot Viktor Axelsen, who won the Dubai Super Series Finals in 2016, is in the third spot. South Korea's Son Wan Ho is also among the top five shuttlers and reigning Olympic champion Chen Long is China's highest-ranked Men's singles player at the fifth spot.
