WWE: 10 Matches WrestleMania 30 Could Set Up For WrestleMania 31

7. Cena Vs Undertaker

The biggest streak match WWE have left in the tank is Cena vs Undertaker. Given Taker's age (he turns 50 before Mania31), they're running out of time to do it. This may press WWE into pulling the trigger and setting in motion the Cena vs Taker feud this year. It would be a massively wasted opportunity if this match doesn't happen before Undertaker retires, Cena is the biggest WWE star in the company and the one last threatening streak match which could take place. The way to establish it a year out could be as simple as Cena coming to the ring after Taker beats Brock and giving him a nod from the stage. The non-verbal communication would be saying 'I respect you, but next year you have to face me.' As we already detailed, it seems unusual for the biggest franchise star in Cena to be just lost in the shuffle of the mid-card against Bray Wyatt at WrestleMania 30. It would all make sense if Mania 30 ends up being noteworthy for Cena from an entirely different bit of the card. Coming out to challenge Undertaker a year out for Mania 31 could be Cena's real WrestleMania 30 moment.
