#1 Doesn't Like: Bill Goldberg
Things may have changed recently, given their feud in 2017 with Kevin Owens, but in WCW, Jericho and Goldberg could not get along.
As one of a few stars WCW made themselves, Goldberg was handed a lot of opportunities, some of which, many wrestlers, including Jericho, thought should've gone to a more established star.

Jericho even took it so far as to begin a feud with Jericho, calling out the former football player, and when Goldberg didn't show, Y2J would count it as a win.
Claiming to be 6-0 against what he called 'Greenberg', the WCW backstage loved the story, though eventually wanted the two to face off in an actual match.
In his book, Jericho said he excitedly told Goldberg the news of the match, to which Goldberg responded, saying he didn't even know they were feuding, and squashed Y2J in minutes.
