#2 Goldberg vs Brock Lesnar (WrestleMania XX)

When WWE first laid the stone for a mammoth program between Brock Lesnar and Goldberg for WrestleMania XX, fans all across the world went into a state of frenzy. After all, it was a fight between two big of the biggest superstars in WWE at that time, and something that the fans had been waiting to see ever since Goldberg made his debut in WWE in early 2003.
However, all the excitement and enthusiasm for the match fizzed out when it was revealed that both Lesnar and Goldberg would be leaving WWE after Mania. Although the inclusion of Steve Austin in to the rivalry, who acted as the special Guest Referee, did raise the interest back some notches, it was never the same. Even then, fans were still expecting these two to give their best on their last night with WWE.
They didn't. Their match at Madison Square Garden was a big, big disaster. Instead of going after each other from the opening bell, the two spent the first half of the match just playing with the crowd and by engaging in boring rest holds.
So horrible was this encounter that the fans cheered for Austin while booing both the competitors in the match, and gave little reaction to Goldber's win. It's a good thing that they made up for it with their match 13 years later with a barnburner of a match at Mania 33.
