WWE Royal Rumble is just a few months away, meaning we're close to starting off the Road to WrestleMania. It might still be October, but it's never too early to start predicting the WrestleMania main event, and Sam Roberts pitched some major match-ups regarding the Women's WWE and World Championships.At this point, two PLEs guarantee four world title bouts at WrestleMania. Unless something changes, we'll see Royal Rumble and Elimination Chamber matches for the men and women. Last year, Charlotte Flair made her return at the Rumble, leading to a loss against WWE Champion Tiffany Stratton. Bianca Belair won the Elimination Chamber, which led to a three-way against Rhea Ripley and World Champion IYO SKY. Now, RawTalk host Sam Roberts believes we could, and should, see IYO SKY competing for the World Title again, this time against Rhea Ripley. On Notsam Podcast, Roberts got into it. "I want Rhea Ripley to win the Women's World Championship from Stephanie Vaquer. I want Rhea to be the one to beat Stephanie Vaquer, and I think that'll be a controversial one, and I think there will be some people upset by that, but it's to get to a bigger picture, which is Rhea Ripley wins that championship, and then IYO SKY wins the Elimination Chamber," Roberts said. [39:30-39:57]Roberts believes that the newfound friendship between IYO SKY and Rhea Ripley could lead to a brand new chapter in their rivalry, which might be enough to main event. "Rhea defending against IYO, I don't want IYO defending against Rhea. I want Rhea defending against IYO. I think that dynamic and that match has the potential to main event one of the two nights." [40:50-41:04]It's not just The Genius of the Sky. Roberts also gave his best bid for the WWE Women's Championship.Could Bianca Belair and Jade Cargill main event WrestleMania for the WWE Championship?The Est. of WWE hasn't wrestled a match since WrestleMania. Recovering from a badly broken finger, Bianca Belair's only appearance in-ring since then was as a special guest referee between Jade Cargill and Naomi at Evolution. Fans have been eagerly awaiting her return, and Sam Roberts believes a little more patience is in order."If you have Jade Cargill win the WWE Women's Championship at Saturday Night's Main Event, and for five months be a completely dominant champion, only for Bianca Belair to return at the Royal Rumble and get the WrestleMania match? If you're saying your two women's championship matches at WrestleMania are Bianca Belair vs Jade Cargill and Rhea Ripley vs IYO SKY? It is one of the strongest sets of championship matches in the women's division that I recall seeing at a WrestleMania," said Roberts [41:05-41:45]Two major title bouts featuring four of the most popular Superstars, all of whom have a lot of history with one another? It would be tough to pitch something better.
