#1. WWE Mistake: The Fiend vs Goldberg
Goldberg had already made quite the impression in Saudi Arabia following his match against The Undertaker, but the former WCW legend made the decision to return to The Middle East to battle the undefeated Fiend at Super ShowDown back in February.

It was thought that this match would be a walk in the park for The Fiend, but instead, it turned into one of the biggest mistakes of the star's career. It was another short match from Goldberg that saw him walk out with WWE's biggest prize.
Not only that but it meant that a part-time superstar was the only man in WWE who had been able to defeat The Fiend. WWE ensured that Seth Rollins didn't defeat Bray Wyatt's alter-ego a few months earlier, just to hand him over to Goldberg who then wrestled one more match at WrestleMania before walking away once again.
It's unknown why Goldberg is still the only man to defeat The Fiend and what this means to his character. It's just disappointing that with all the talent on WWE's roster and everyone that could have used that push, it was Goldberg that was chosen.
