We all know Cena and Rusev are going to end up feuding eventually as it just makes too much sense for them not to and we all have the fear that Cena, the Conqueror Of Undefeated Streaks (Undertaker's Wrestlemania record being the exception), will be the first to defeat "The Russian Brute", but who thinks it could happen as early as Hell In A Cell or Survivor Series? If Cena ends up taking another clean loss to Brock Lesnar at Night Of Champions, then you can be damn sure he's winning his next feud as a way of "gaining his credibility back", and with who else might that be other than Rusev? Seth Rollins will be tied up with Ambrose, and defeating Corporate Kane just wouldn't be nearly as significant as being the first to trounce Rusev, and I don't see nay other viable options. I could even see them having this match headline the Tribute To The Troops show in December since it's so close by. (It could also be why Rusev isn't going after the United States Championship right now because the US Title would clearly have no place in a feud with Cena.) Of course, I could also see them waiting it out until Wrestlemania and booking it as a midcard feud, ala Cena vs Wyatt this year, but I wouldn't be shocked to see them pull the trigger on it this early. Viewing things from WWE's point of view, I could see them booking this as Cena's big redemption moment following two consecutive losses to Brock Lesnar.
