#1 CM Punk
Soon after WrestleMania 27, CM Punk cut one of the greatest promos in WWE history, now famously known as The Pipebomb. He promised that he would defeat John Cena at Money In The Bank 2011 and leave the company with the WWE title on his shoulders.
Vince McMahon did everything he could to prevent that from happening, but Punk defeated John Cena in a 5-star classic to win the WWE title. Immediately after, Vince called out Alberto Del Rio to cash in his MITB briefcase on Punk, but he was put down with a kick to the head as soon as he entered the ring.

Punk left WWE but returned in a matter of days to continue his feud with John Cena. At SummerSlam, the two met again in one of the most anticipated rematches of all time. When all was said and done, Punk defeated John Cena again to retain his WWE title.
This was almost a decade ago when John Cena losing two major back-to-back matches was a rare occurrence. Unfortunately, Punk lost the title minutes after, due to an attack by the returning Kevin Nash and a cash-in by Alberto Del Rio.
