#9 Beth Phoenix

The legendary Beth Phoenix, who had entered the men's Royal Rumble match and eliminated the Great Khali earlier in her career, may well be looking to enter her 3rd Royal Rumble match in 2019. Beth Phoenix was even a part of the first-ever women's Royal Rumble match in 2018 where she was eliminated by Natalya.
Given that the Royal Rumble PPV is taking place in a baseball stadium this year, the WWE may announce Beth Phoenix's entry before the show.
#10 Michelle McCool

Another legendary superstar who may return to the squared circle once again at the Royal Rumble PPV, Michelle McCool holds the record of the most number of eliminations in a women's Royal Rumble match.
She had eliminated Sonya Deville, Liv Morgan, Molly Holly, Lana and Vickie Guerrero in 2018 and would definitely want to better her 2018 record in 2019.
