#2 Charlotte Flair (WWE Women's Tag Team Championship)
Since the introduction of the Women's Tag Team Championship last year, women could become WWE Grand Slam Champions too. The four titles in question are the RAW, SmackDown and NXT Women's Championships, along with the Tag Team Titles.
Bayley was the first one to achieve it after her SmackDown Women's Championship victory at last year's Money in the Bank, with Asuka following suit a year later with the RAW Women's Championship. Another few women's Grand Slam Champions will be coming in the future, with Charlotte Flair a likely candidate.
Having won the three singles titles a combined 11 times, all Charlotte has to do to win the Grand Slam is co-exist with a tag team partner and win gold with her. Her superior being on the roster makes it unlikely to happen any time soon. The Queen has challenged for the Women's Tag Team Championship before, alongside Becky Lynch in a losing effort to the Kabuki Warriors at TLC.
With the grandeur in which WWE has presented Charlotte, expect them to give her a short tag title reign at some point, even if it is only to make her a Grand Slam Champion.
If Becky returns to WWE following her pregnancy, Charlotte Flair could have a mini-reunion tour with her and win the Women's Tag Team Championship for a short while.
