Bret Hart is a two-time WWE Hall of Famer, but it appears that he still harbors a grudge against a fellow superstar.

Goldberg and Bret Hart faced off at WCW Starrcade 1999. The WCW legend delivered a botched superkick which gave Hart a concussion.

The WWE Hall of Famer recently appeared on Steve Austin's Broken Skull Sessions where he talked about the match and called Goldberg "unprofessional":

"I just wish some of the wrestlers I worked with especially in the end like Goldberg - Goldberg to me was one of the most unprofessional wrestlers there was in the business. I mean for Bill Goldberg to be in the Hall Of Fame. He hurt everyone he ever worked with. You might as well wrestle a real gorilla.He was the most dangerous guy to work with. He hurt everyone he worked with."

Bret Hart holds a grudge against the man who ended his wrestling career, but Goldberg has continued to wrestle in recent years and is now a former two-time Universal Champion.
