WWE Saturday Night's Main Event on December 13 is set to feature Cody Rhodes taking on Oba Femi. The show will conclude with John Cena taking on Gunther in his final WWE match, while the remainder of the event will put the spotlight on younger talent in NXT.This past week, it was announced that the NXT Champion after Deadline would take on Cody Rhodes at the TV Special. Oba Femi defeated Ricky Saints to become a two-time NXT Champion and will now battle The American Nightmare in what promises to be an incredible bout.In this listicle, we will take a look at four ways the match between the two champions could conclude at Saturday Night's Main Event.4. Oba Femi could win cleanThe Ruler is set for the biggest match of his career so far when he faces Cody Rhodes. His sheer dominance on the developmental brand has made him one of the biggest stars of the future for WWE.While Rhodes is firmly at the top of the mountain right now, he could be overcome by Femi this weekend. The NXT star has the physical superiority and could earn a clean victory over the WWE Champion. However, this scenario is unlikely as the company would want to protect Rhodes as he is still one of the top draws of the promotion.3. Ricky Saints could interfere to cost Oba Femi the matchThe Nigerian defeated Ricky Saints at Deadline to reclaim the NXT Title and earn his shot at Rhodes. The rivalry between the two doesn't seem to be over despite a show of respect after their match in the form of a handshake.Saints could end up interfering in the match, and could cost his rival the win to reignite their rivalry and make it more personal.2. Cody Rhodes could win controversiallyThe American Nightmare hasn't exactly earned a lot of clean victories since his comeback in the summer. He used the exposed turnbuckle to win the King of the Ring tournament this year and used the title behind the referee's back to defeat Drew McIntyre in his most recent title defense.Rhodes must be aware that Oba Femi is faster and stronger than him and could overpower him easily. Therefore, he could once again find a way to bend the rules and could earn the win by using a foreign object or the exposed turnbuckle without the referee catching him in the act.1. Drew McIntyre could interfere in the matchDrew McIntyre and Cody Rhodes' feud was rekindled this past week on SmackDown when the Scottish Warrior was attacked in his own car by Rhodes. While McIntyre is still suspended from SmackDown, he is free to appear at Saturday Night's Main Event and could interfere to cost Rhodes the match.Since WWE will likely want to protect both Oba and Rhodes, the Scottish Warrior's interference could lead to the match ending in a no-contest if he attacks both stars. Since a third title match between the two seems imminent, this would be the best way to set up another clash while protecting both stars.
