Samoa Joe debuts and challenges Cena
The former NXT champion has been a major part of the rumor mill with a speculated debut at the Royal Rumble. The WWE can bring him to the main roster at the PPV in two ways. If Cena wins the WWE championship match, then Samoa can interrupt the victory celebration by setting up a match at Wrestlemania. This will be a dream match for the WWE fans ever since the Samoan superstar signed a contract with the WWE. The second option is by making him the Royal Rumble winner upon his WWE main roster debut which will turn out to be a mind-boggling idea. In both cases, fans will go wild.
