The Rock as everybody knows has announced that he is never leaving WWE permanently meaning he will be appear occasionally after his fued with Cena is at an end. Amidst rumours that he has already signed on for matches at Summerslam, Survivor Series and WM 29 I'm wondering who you would like to see him fued with next./QUOTE]
Having watched my share of pro-wrestling between mid 90s and early 2000s, I feel like I have seen enough of Rock vs. HHH. (Besides that would contradict the whole "Two last outlaws" angle they have with HHH and Undertaker.) I think it would be better if he went against current stars.
Also, since he is pretty much guaranteed to be loved by the fans no matter what, he should wrestle heels rather than faces. I think a Wade Barrett-Rock rivalry would be cool. Barrett is great on the mic and already has a reputation for taking Cena and Orton to the limit. A rivalry with Rock would further cement his main event status.
Another one could be Cody Rhodes. He is already having it out with other veterans of the WWE, like Booker T.
