5. Daniel Bryan
If you don't want to see CM Punk face Daniel Bryan, especially at WrestleMania, then you are either not a true wrestling fan, or you don't know how good these two really are.
Daniel Bryan and CM Punk go back as far as their days in ROH, which is known and made famous from it's high quality wrestling as well as phenomenal wrestlers.
It was there that these two men made their mark as two of the best wrestlers in the world today, and where they created many classics, some with each other.
They have faced off against one another in the indies, but WWE fans have never seen these two go one-on-one, so it is the IWC's dream for WWE to finally bear witness to a Bryan v.s Punk, and what better place than at WrestleMania.
We got a taste of that at the Royal Rumble earlier this year when these two started off the Rumble match itself. Judging from that, it would be an all-out classic if these two had 20 minutes to wrestle.
Daniel Bryan is cashing in his Money in the Bank at WrestleMania 28 for the World Title, so it's unlikely that they will face off, but it's still possible, and with how the WWE is today, anything can happen.
