Who will end Flair's career?

As most of us know, if Ric Flair loses one more match he is forced to retire. But who will be the one to beat him? Take a look below:

Who will be the one to end Flair's career?

Mr.Kennedy: He has made a career out of beating his superiors. Ric Flair could be next.

Shawn Michaels: He is friends with Flair, but they could be put in a friend vs. friend match.

Edge: He and Flair don't really have a good history together. Maybe they will sqaure off soon.

MVP: He swore that he would end Flair's career. Maybe he will.

These are all good ideas, but I think John Cena will end Flair's career. It will give the Cena haters something else to complain about, and it will add to his alustrios career.
