#4 Another Greatest Royal Rumble
In the announcement made by WWE, they haven't mentioned the name of the event that will take place next month in Saudi Arabia. The first PPV here last year was called "The Greatest Royal Rumble" as it featured for the first time a 50-men Royal Rumble match, which was won by the Monster Among Men, Braun Strowman.
While we still don't know whether that was a one-time deal or not, but there is a chance that WWE might return with the 50-man royal rumble this year as well. If it indeed goes down, we might see some legends return for a small stint.
Even someone like Goldberg would do better in such a match as he's not really known for his wrestling abilities and to carry on a long 15-20 minute match. If I were to pick a winner this year, I'd go with either Lars Sullivan or Drew McIntyre.
