I think LXR's threat won't come from any of her well-known rivals who can only hope to catch her on her off day. I'd look to the new crop of up-and-coming,promising youngsters to see who might pose a serious challenge to her in the near future, say, Mitani Minatsu, Nozomi Okuhara, P V Sindhu, Deng Xuan, Sun Yu, for example. For me, I especially like Sun Yu who is said to be in the mould of Wang Yihan with the height and reach.
Understandably, LXR's sudden ascent to the pinnacle has evoked mixed reactions, from being bowled over to grudging acceptance. She herself is aware of that and has said she is determined to do her utmost and start garnering as many titles as possible within the shortest time. And, I hasten to add, she is beginning to live up to her words, collecting her third consecutive world class titles in just two months; many more to come, I believe.
