I have no idea in what realm Goldberg would ever lose to Jericho. Goldberg refused to wrestle Jericho in WCW because he thought it was completely unbelievable that he would do anything but destroy him. Jericho is a great wrestler, and I much prefer him, but Goldberg lost like 7 matches in his entire career and Jericho isn't going to be able to beat him twice in one night.
