In terms of that knockout blow, you're absolutely right - Cena's sooo good on the mic, if you come at him with the same thing everyone else has been saying for over a year then his responses will only get better (as Roman found out).

It's interesting though because how would you go at Cena? I think Punk genuinely did it best with the "you are what you hate" angle which was genius. Took me a while to find it but this promo from Punk (at the 20min mark) is epic (the whole thing is being honest): https://www.youtube.com/watch?v=FouccjzEEPU
