John Cena intimated that he wanted to get a rematch with the Rock at WrestleMania 29 on Larry King Live. Cena, CM Punk and others were interviewed in Sacramento for King's show and when asked who his favorite opponent is, Cena replied that it was the Rock because Rock beat him at WrestleMania. Cena noted, "I really want to beat him."
As to his physical condition, Cena noted that he's got his elbow injury but feels far better now than he did at twenty years old. When asked how much longer he thinks he can physically compete for the company, he said that he would continue wrestling until he couldn't hang with the younger talent anymore. He also noted that he believes he will be with WWE after his in-ring career is done, saying, "I do believe so. This is my passion."
King asked Cena if he will "run this thing," to which Cena laughed and said, "I don't know. A guy named McMahon who would probably battle me for that."
We posted this video earlier and it's definitly worth checking out. This is a really good and must-see video guys.
Video of the interview is below; apologies to non-US customers but it is Hulu, so it may not play internationally.
