#3 Randy Orton vs Christian

The most famous rivalry of 2011, the one which got the WWE universe on their toes as two technically gifted superstars collided for the World Heavyweight title. Orton and Christian were a delight to watch together and their in-ring chemistry was appreciated by the wrestling enthusiasts.
What made this rivalry so special was how Christian at first won the world title after years of struggle and then Orton coming out and challenging for the title. At one point this was tipped as the battle of faces since both the superstars got major backing from the WWE universe but as the rivalry progressed, Christian turned heel.
WWE carried out the idea that however hard Christian tries, his attempt of winning back the title fails. The two competed in a number of PPVs in 2011 like Summerslam, Money in the bank, Over the Limit and more.
All in all, while Christian did win by disqualification at the 2011 edition of MITB, other than that, this rivalry was all about Randy Orton being the dominant one.
