#4. Don't Want: Charlotte Flair vs. Becky Lynch vs. Ronda Rousey/Flair vs. Rousey

At first, it seemed that this would indeed be the match for Ronda Rousey at Wrestlemania 35. But when Becky Lynch wasn't cleared to face Rousey at Survivor Series due to a reckless strike from Nia Jax, WWE decided to have the Flair vs. Rousey match in November instead.
While it ended in a disqualification due to an attack from Flair in order to keep her looking strong and on the same level of Lynch and Rousey, we all knew that they would cross paths once again.
Lynch is now cleared, so several people have figured that Lynch vs. Rousey might be the first-ever women's match to main-event a Wrestlemania.
But Vince McMahon loves Charlotte Flair and always wants her at the top or chasing the top of the card. He wants her to be a member of the historical match regardless of if it should simply be a singles match between the Man and Rousey.
They haven't had a singles match yet but some recent rumors suggest that WWE will probably have that match before April in order to secure the triple threat match.
Flair seems like she's a third wheel in the feud and she is. She could easily feud with Asuka again at the show and hopefully, lose this time.
Whatever the case may be, Rousey and Lynch were the ones who were on fire during their feud and adding Flair to the mix screams of WWE having to control the situation.
