6. Costing Seth Rollins The WWE Title
One of the all time best pops in WWE history was when Stone Cold Steve Austin turned up and cost The Rock his WWF Title against Mankind on Raw. How cool would it be to see John Cena doing the same thing to Seth Rollins? To set the scene, it would be late December, and Rollins would be defending his title on Raw against an underdog. Perhaps it could be fan favourite Dean Ambrose. Just as it looked like Rollins was about to cheat his way to victory with the ref down, Cena's music would hit and he'd come out for the save. He'd then hit the AA on Rollins and place Ambrose over the decked champ. The ref would then count one two three! It would be a sensational way to bring Cena back, and also a hell of a moment for Ambrose and Rollins to be involved in.
