Pyongyang, November 21 (KCNA) -- Prof. and Dr. Ri Tong Gyu (75), who is a researcher at the Sports Science Institute under the Academy of Sports Science of Korea, is popular among local people as a TV football commentator.

His explanation, artless and intellectual, is based on a wide-ranging professional knowledge covering tactics and records of any teams, footballers and coaches all over the world.

Football matches supported by Ri's explanation draw more TV viewers.

Ri had served for sports development of the General Association of Korean Residents in Japan (Chongryon) before he returned to the homeland. After returning home, he has trained many people as sports scientists and made scores of valuable research findings.

He appeared on TV more than 900 times to explain local and international football matches.

Leader Kim Jong Il sent a birthday spread to him, appreciating his services for the development of the country's sports science.

Old as he is, he is still energetically working for the development of the nation's sports science, including football techniques.
