Vimal Kumar has seen Indian badminton travel through valleys and peaks. From Pullela Gopichand winning the All England to Saina Nehwal becoming world No.1 and PV Sindhu being crowned world champion, Vimal has witnessed it from the vantage point of a player, coach and manager. But when India slammed all the comeback doors on Indonesia in the Thomas Cup final on Sunday to be crowned champions, he said, "This is the best achievement of Indian badminton." Thomas Cup win: Wish Team IndiaAfter Malaysia in the quarterfinals and Denmark in the semis, India completed a hat-trick of giant-kills by stunning defending champions Indonesia 3-0. It was in a way reminiscent of India beating the mighty West Indies twice at the 1983 World Cup, including in the final, to win the trophy. Vimal didn't disagree.
