#3 Wants to return: Alberto Del Rio

Alberto Del Rio achieved almost everything there is to achieve during his first run with WWE between 2009 and 2014, winning the Royal Rumble, Money In The Bank, WWE Championship (x2) and World Heavyweight Championship (x2).
During his second run, which began in October 2015, he won the United States Championship on two occasions and was part of the League of Nations, but he was unhappy with his position on the roster and was released from his contract in September 2016.
