Indian badminton star Lakshya Sen on Friday said he has worked on his net game and the recent trait of conceding points late in a contest as he prepares in Marseille, France for the Paris Olympics starting next week. The world No 19 has been drawn in Group L along with Indonesian rival Jonatan Christie (WR 3), Guatemala's Kevin Cordon (WR 41) who finished fourth in Tokyo Olympics, and Belgium's Julien Carragi (WR 52). "We have focused a lot on overall improving the game and we had a good time for the last 6-7 weeks where I could really work on all the areas of the game," Sen replied to a PTI query during a virtual interaction.
