John Cena vs. CM Punk (2011)
For the first time in WWE's history, we had two WWE champions in John Cena and CM Punk going into SummerSlam 2011. Punk had left the company with the title in tow when he walked out at Money in the Bank, and Cena had won a tournament to crown a new champ in his absence.
Thus, the stakes were higher than they had ever been before, for their impending clash at SummerSlam. And with Triple H appointed the special guest referee for the bout, fans knew shenanigans would likely ensue.
Thankfully, that was hardly the case as Cena and Punk delivered yet another awesome match as only they were capable of. Aside from a convoluted conclusion that saw Cena's foot on the bottom rope when Punk pinned him for the win, their Money in the Bank rematch was every bit as exciting as fans hoped it would be.
