WWE is just five days away from hosting Saturday Night's Main Event XLII, and fans eagerly anticipate what the creative team has in store for them. The event will see John Cena officially hang up his wrestling boots after facing his final opponent, Gunther, who emerged as the winner of The Last Time is Now Tournament by defeating LA Knight in the finals.Meanwhile, the upcoming event won't be a traditional SNME. Instead, it will feature exhibition matches and will include stars from NXT. At the request of John Cena, who wanted to see a card stacked with the stars of the future facing off against current stars, Cody Rhodes will now go toe-to-toe against Oba Femi.Femi defeated Ricky Saints last Saturday at NXT Deadline to regain the NXT Championship. He had previously lost the title to the former AEW superstar at NXT No Mercy earlier this year. Not only has the victory given the Nigerian contender another taste of championship gold, but he will also take part in a Champion vs. Champion match against The American Nightmare at Saturday Night’s Main Event.Given that the undisputed WWE Champion will be stepping into the ring with an opponent he has never faced before, there is a possibility that he might not come out victorious at the upcoming event. To ensure that Cody wins while also keeping Oba Femi's momentum, the creative team could book Ricky Saint to interfere in the match and cost Femi in Washington, DC.Interestingly, considering that Ricky shares a great friendship with The American Nightmare in real life, it could lead to the duo joining forces as a team. Since the 35-year-old star quickly found success in the promotional brand after signing with the company earlier this year, Cody Rhodes could benefit from working with him on the main roster.However, while this angle might sound convincing, it is speculative, and fans will have to wait until WWE Saturday Night's Main Event to see if it comes to fruition.John Cena could lose to Gunther at WWE Saturday Night's Main EventJohn Cena is set to bid fans farewell at WWE Saturday Night's Main Event in Washington, DC. He will be facing his final opponent, Gunther, as an active wrestler. However, there is a great possibility that the GOAT might lose in his retirement match.Gunther has been rumored to be Cena's final opponent even before the Last Time is Now Tournament commenced. Furthermore, his dominance in all the matches of the tournament suggests that The Ring General is the fan favorite to defeat The Franchise Player.That said, this is also speculative, and it will be interesting to see who secures the victory at SNME.
