林丹
Lin Dan entered 2007 with a loss to South Korea's Park Sung-hwan in the round of 16 at the Malaysia Open. A week later he captured the Korea Open by defeating Chinese teammate Chen Jin in the final. He went on to win the German Open and then the All England championships again, crushing compatriot Chen Yu 21–13, 21–12. In June, Lin Dan was part of the Chinese Sudirman Cup team that retained the cup after beating Indonesia 3–0 in the final at Glasgow, Scotland. Later in the season Lin Dan defeated Wong Choong Hann of Malaysia and became the China Masters champion for 2007. In August, Lin Dan extended his reign as the world champion when he beat Indonesia's Sony Dwi Kuncoro 21–11, 22–20 in the final of the tournament held in Kuala Lumpur, Malaysia. Lin Dan thus became the first man since Yang Yang to win back to back world championships.
