#2 Retired this year: Goldberg
Goldberg returned to WWE in 2016 and instantly shocked the wrestling world when he defeated Brock Lesnar at Survivor Series in less than 90 seconds. Goldberg later won the Universal Championship from Kevin Owens but lost it to Lesnar at WrestleMania 33.
It was his final wrestling match until he made his return again for Super ShowDown. WWE booked Goldberg vs The Undertaker in Saudi Arabia, which was seemingly the worst match of both Superstars. Not only did we see multiple botches, but it was also clear that Goldberg was having issues performing almost every move.
A majority of fans believe that Goldberg should retire from wrestling because if he doesn't then he could seriously injure himself of his opponent, which shouldn't happen. Goldberg is past his prime time and it would be better if he never wrestles again.
