Get ready for a snowball in hell ... 'cause sources tell TMZ Sports pro wrestling legend Bill Goldberg is in talks with WWE honchos about a possible return to the squared circle.
It's huge news considering Goldberg HATED Vince McMahon when he left WWE back in 2004 -- and repeatedly vowed to never work for the company ever again.
But Goldberg recently struck a deal to appear in the WWE 2K17 video game -- and sources tell us the two sides are now talking about expanding their working relationship.
