#1 Charlotte Flair

Charlotte Flair won the SmackDown Women's title at Money in the Bank after defeating Becky Lynch, becoming the nine-time women's champion.
But moments after winning the title, Bayley cashed-in on the Money in the Bank contract that she won earlier in the night, and won the title in no time - her first SmackDown women's title.

Bayley and Flair have history, having feuded in NXT way back in 2014, and later on RAW in 2016. They are both supremely talented Superstars in the ring and have put on great matches in the ring.
With reports suggesting that WWE are keen on Charlotte matching her father, Ric Flair, with 16 world titles, we could maybe see Bayley and her exchange titles over a few PPVs. With Becky Lynch out of the picture, Charlotte Flair is the biggest name on the SmackDown roster.
