9. Alberto Del Rio
WWE.comAlberto Del Rio is a four time WWE and World champion. He is one of the most talented workers in the company and by far one of the best heels. Del Rio is very easy to be hated and he deserves every ounce of respect that he has earned. And he would be a great addition to the hit list of one Roman Reigns. Del Rio did not have all that much interaction with The Shield, mostly due to the trio being heel for most of their run. Because of that, facing off against Roman would have the feel of something new and fresh for fans. And the match itself could be hyped from day one as the bout of the firmly established star versus the guy that is still building his legacy. Alberto is definitely one of the most hated antagonists that WWE has and the heat he has with the crowd would do nothing but get Roman over even more. After all, who doesn't want to see a heel get his? Roman would be the man to do that and the fact that Alberto is so highly decorated in the company would only help his cause. Reigns would have the the distinction of being a new singles star that pinned a four time world champion and that could mean the difference between working toward the main event and actually getting there. Roman would get the rub from Del Rio and take it up the ladder with him. And that's exactly what he needs.
